kandi X-RAY | fractal Summary
Fractal provides a presentation and transformation layer for complex data output, the like found in RESTful APIs, and works really well with JSON. Think of this as a view layer for your JSON/YAML/etc. When building an API it is common for people to just grab stuff from the database and pass it to json_encode(). This might be passable for "trivial" APIs but if they are in use by the public, or used by mobile applications then this will quickly lead to inconsistent output.

QUESTION
I have a data frame. One column is called fractal. It has 0's or 1's in which the 1's represents a fractal. Here is the output of np.flatnonzero to get an idea of the frequency of fractals:

QUESTION
I am trying to make a program in turtle that creates a Lyapunov fractal. However, as using timeit shows, this should take around 3 hours to complete, 1.5 if I compromise resolution (N).
...ANSWER
Answered 2022-Mar-29 at 23:02On my slower machine, I was only able to test with a tiny N (e.g. 10) but I was able to speed up the code about 350 times. (Though this will be clearly lower as N increases.) There are two problems with your use of update(). The first is you call it too often -- you should outdent it from the y loop to the x loop so it's only called once on each vertical pass. Second, the dot() operator forces an automatic update() so you get no advantage from using tracer(). Replace dot() with some other method of drawing a pixel and you'll get back the advantage of using tracer() and update(). (As long as you move update() out of innermost loop as I noted.)

I am using laravel-repository pattern ,i have one api which is responsible for getting all users it's working fine ,if we are using that package by default search should support for that i set $fieldSearchable array in the repository class.
i hit an api like this localhost.com/api/lists?search=foo,it's not working can you please help me where did i mistake
UserController.php

Answered 2022-Mar-24 at 16:27It maybe resolved by utilising pre-difined methods No need to write show() function logic because by default l5-Repository pattern contains some methods to get all the data all()or paginate().in your controller write like this in getUsers()

I want to find the highest price and exit when current price is lower than highest price. The code to find the highest price is copied from here. how can I make a simpler code that finds highest price since entry? I also want to close the deal if current price is lower than a specific price. Please help me.

QUESTION
I created a fractal animation using JWildfire. It consists of 5772 1024x768 still images. I tried importing all of the images into OpenShot one step and had serious problems. So, I broke it down the three "parts" of 1924 images apiece. That was still problematic, but I got the images imported. However, only the first 1924 will animate and when I tried to do subsequent video frames like I did with the first 1924 images, OpenShot would indicate that the first image in the set was not valid. However, I tested it and even resaved it and it would open in other apps without a problem. So, I imported the last two sets of 1924 without creating the video frame (I don't recall the exact term) thinking that I could edit the first frame to include all 5772 images. Apparently, I was wrong. How can I fix this so that it will play through all 5772 images rather than just the first 1924? The PC that I have is far from top notch. Here are my specs:
Processor Intel(R) Core(TM) i3-3225 CPU @ 3.30GHz 3.30 GHz Installed RAM 8.00 GB (7.88 GB usable) Device ID 87BC0DCC-B603-4158-9700-09CEF99A171C Product ID 00330-80000-00000-AA170 System type 64-bit operating system, x64-based processor Pen and touch No pen or touch input is available for this display
Edition Windows 10 Pro Version 21H2 Installed on 7/11/2020 OS build 19044.1503 Experience Windows Feature Experience Pack 120.2212.3740.0
I'm using OpenShot 2.6.1 64-bit. Any help is greatly appreciated. Thanks.
...ANSWER
Answered 2022-Feb-28 at 02:16I solved my problem by installing Shotcut. It made creating three separate image sequences and adding them to a timeline trivial. Now, the animation plays through seamlessly just as it should. Shotcut seems to be written much better. It doesn't take up nearly as much RAM with all 5772 images loaded. It wasn't anywhere near as problematic to get all of those images loaded and creating the three image sequences was super easy. The UI isn't very "shiny", but it gets the job done. So, goodbye OpenShot and hello Shotcut! Oh, and the xml/mlt movie file is much smaller than the osp movie file. So, that's awesome too.
QUESTION
I have a working fractal H tree here that randomizes the color in terms of the whole tree at once being a randomized color.
However, I wanted to try and get each individual fractal (each recursion) to be a random color. I am not sure how to do this and have tried to find solutions but have come up short.
I am kinda new to some of this stuff so sorry if this is a silly problem

QUESTION
I am doing a very simple test using the Williams Fractal indicator that I copied directly from the standard one in Tradingview "as is".
I am trying to enter the trade when downFractal is true, exit it when upFractal is true.
The results of the strategy are completely inconsistent with what they should be as for the plotting and, for the love of me, I honestly cannot understand why. Maybe I am not using boolean variables right?

QUESTION
I have started building a mandelbrot viewer application with WebGL2 and JavaScript and am trying to implement series approximation at a basic level. I'm currently getting weird/distored/incomplete images depending on the number of iterations and the reference point I'm using (currently just the center of the viewport in the complex plane).
I don't have a heavy math background so it's entirely possible (apparent) that I've screwed up my calculations somewhere. I know there are separate concerns with choosing reference points, the number of iterations that can be done with the coefficients without distorting the image, etc., but I'm just trying to see the basic concept working. Currently I am only skipping 1 iteration with a reference point near the origin (-0.5, 0.0), and I don't think the result is supposed to be this distorted.
If someone is able to see and explain to me where the logic in the code has gone wrong to produce this result I would greatly appreciate it. I'll try to include all of the relevant code, including the fragment shader and JavaScript code so you should have all the information needed.
fragment.glsl
...ANSWER
Answered 2021-Nov-06 at 18:31I solved my own problem. The coefficients and the current "xn" (z) value were out of sync by 1 iteration. Re-reading this paper helped me realize that I was skipping an iteration of x which throws off the delta n calculations. I now have a better idea of how to apply the same logic for other reference points besides the center of the screen (should just have to add the distance of x0 from center when computing delta 0) and can begin exploring optimizations like choosing good reference points and detecting glitches, calculating how many times to iterate with the coefficients, etc.
The fractal looks normal with the x sub 0 coefficients plugged in at broad zoom levels, and when applied beyond that becomes increasingly accurate at deeper zoom levels like it's supposed to. Relevant fixed code:

QUESTION
So I'm a fractal enthusiast and decided to build a 2D/3D fractal generator in WebGL using raymarching, with Typescript as scripting language. I've been a C#/Typescript dev for several years but having zero experience with 3d programming, I used Michael Walczyk's blog as a starting point. Some of my code I use here is derived from his tutorial.
I added the functionality that you can move through the object using WASDQEZC keys. WS = strafe forward-back, AD = strafe left-right, QE = strafe up-down, ZC = roll left-right. I combine this with a mouse look function which moves in the direction the mouse pointer is located on the rendering canvas. So what I want is total freedom of movement like in a spacesim. For this I am using a separate camera rotation matrix together with translation values and send them to the shader like this:

Yesterday I came across the new 3Blue1Brown video about Newton's fractal and I was really mesmerized by his live representation of the fractal. (Here's the video link for anybody interested, it's at 13:40: https://www.youtube.com/watch?v=-RdOwhmqP5s)
I wanted to have a go at it myself and tried to code it in python (I think he uses python too).
I spent a few hours trying to improve my naive implementation and got to a point where I just don't know how could I make it faster.

Install fractal
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
