QUESTION
I'm working on a Python script that takes a mathematical function as an input and spits out useful information to draw a curve for that function (tangents, intersection points, asymptote, etc), and the firststep is finding the definition domain of that function (when that function is valid eg: 1/x-2 df=]-∞,2[U]2,+∞[) and I need to do it using sympy. Down bellow is the WIP code
...ANSWER
Answered 2019-Apr-27 at 22:15This question is similar to How to know whether a function is continuous with sympy?
This can be done using continuous_domain
as explained here.
QUESTION
I'm working in Python to answer this question about whether a group of aliens should bring a population of 5 million and a resource load of 1 million vs population of 1M and load of 5M... I'm trying to find out which of the 2 options would maximize the population on a new planet after after 200 years. Here is my code:
Here is my derivative function
...ANSWER
Answered 2019-Feb-22 at 20:50I don't see where t
is defined in your code but the issue appears to be arising (as you suggest) from t[200] != 200
. This would be relatively easy to check by just adding a print t[200]
line.
If this is indeed the case, you'll want to either determine the index for which t==200
or interpolate. I'd lean toward interpolating with numpy.interp since this will allow you to investigate times that are not integer multiples of your timestep.
QUESTION
I want a 2D cubic spline fit to some irregullary spaced data - i.e. a function that exactly fits the data at the given points - but can also return values in between.
All I can find (for irregural spaced data) is scipy.interpolate.SmoothBivariateSpline
. I can't figure out how to turn 'smoothing' off (no matter what value I put in the s
parameter.
I did, however, find I can get mostly what I want with scipy.interpolate.griddata
- though this has to recalculate it every time (i.e. doesn't just generate a function). Is there any difference, fundamentally between these two - i.e. is griddata
doing something different than a 'spline'? Is there anyway to turn off smoothing in the SmoothBivariateSpline
or an equivalent function that doesn't smooth?
The following is a script I'm using to test fitting of a spline vs a polynomial
...ANSWER
Answered 2019-Jan-30 at 20:06For unstructured mesh, griddata
is the right interpolation tool. However, the triangulation (Delaunay) and the interpolation is performed each time. One workaround is to use either CloughTocher2DInterpolator
for a C1 smooth interpolation or LinearNDInterpolator
for a linear interpolation. These are the functions actually used by griddata
. The difference is that it is possible to use as input a Delaunay object
and it returns an interpolation function.
Here is an example based on your code:
QUESTION
I am trying to download the ngx_pagespeed module so I can compile Nginx from source with it.
I'm using Ubuntu 16.04.
I am using the instructions from https://www.modpagespeed.com/doc/build_ngx_pagespeed_from_source
So I need to install the Ubuntu dependencies first, no trickiness there.
...ANSWER
Answered 2017-Nov-12 at 05:50I'm no bash expert, but wouldn't the second line negate the first?
Yes, first line will be redundant.
Echo the variable again, but this time it returns "1.12.34.2-". Seriously, what is going on here?
This is bash substutution. Construction ${VAR/substring/to replace}
just replaces substring
to to replace
in $VAR
. So, you just stripped "stable" string, this behavior is correct.
I'm starting to think that something is seriously wrong with the documentation. I thought it was just me, but the fact that the variable "NPS_RELEASE_NUMBER" is returning such odd results leads me to believe that something else is going on here.
Looks like this script is over-engineered. Ignore it. Just download/unpack sources of nginx and your modules and then, in directory of nginx do:

QUESTION
so I have this planet simulation in which I'd like to plot the position of the planets (so an unbroken line that follows the planets as they move around) and have tried using so many different variations of linespec. I believe the problem might be because I use a "set(h..)" function first and then plot within a loop but I'm not sure.
...ANSWER
Answered 2017-Jan-13 at 16:29Your plots for each planet are line plots with a single point (plot3(0,0,0,'k.',...)
). This means that when you specify a marker, your single point will be equipped with a marker and that is how you see it. Currently, you are using the dot marker ('k.'). If you remove the dot, there is no more marker and also no line since there are no two points to connect.
Your set(...)
updates the plot not by adding points to it but by moving the single point you plotted originally. To see what happens, type inspect(h_mercury)
, you will notice that its XData
, YData
, ZData
contains only a single point.
If you want to draw lines with the previous points, you need to add them to the plot. There are at least two ways:
- Add a
plot3(p_mercury(1),p_mercury(2),p_mercury(3),'k.'))
to your loop. This will put additional plot points at all the positions that were already visited. Though this is simple it's not necessarily the best: there will not be a solid line connecting the dots and if you make a lot of steps this will add a lot of points and hence make the animation slow. If you want to use this, you also have to delete thehold off
command at the end of the loop since otherwise theplot3
clears the plot. - Better: Memorize the trajectory in an array and have two plots, one for the current position (dot marker), one for the trajectory (line). Something like this:

Install PSOL
You can use PSOL like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
