QUESTION

2D FFT from MATLAB to Python

Asked 2019-Oct-10 at 13:22

Most of my programming experience is in MATLAB and I recently started get familiar with Python.

I came across some great MATLAB code here that pertains to some things I'd like to work with, so I've tried to recreate it in Python:

I only have a partial answer.

If you look closely, the colors on the sinusoidal image generated with your Python code and the one generated with Matlab code you linked have inverted color (check the colors of the stripes closer to edges, and the colors on the color bar).

That explains why you have inverted colors on the FFT plot, and may be why you got 3 Hz, instead of -3 Hz. Unfortunately, I do not have access to a computer with Python right now and won't be able to verify this. I guess this may be a good thing to start troubleshooting with.

EDIT:

Yes, you are right. I completely missed the flipud in the Matlab script. I do no think your c calculation is wrong. The easiest way to check that is to save the Matlab data and import it to Python.

In Matlab:

As you say window<-.ts() uses window() internally to create the new object. It's done via eval.parent(), where window() is called with extend=TRUE, and this is when the error occurs. As such we can simplify our analysis by instead considering the following pair

You're passing the computed x coordinate as the parameter for the y coordinate function, but you should be passing i:

QUESTION

Making my R function faster

Asked 2017-Aug-28 at 06:20

EDIT: Sorry for the low quality post. I should have taken more time to present this to you. The post has been edited, I've added a working syntax example for the whole thing. Thank you to everybody who has offered advice so far.

EDIT2: Found that script is only slow on the other computer. Probably caused by some local issue, or the REPL.

I made this function. It produces frequency tables of values in a labelled (labelled & haven packages) data frame. It works, but I intend to use it on data frames with a lot of columns and I think it runs a bit slow; a user may think R has crashed when running it over 100+ columns, so I would like to speed it up.

The point of this script is to produce output that helps me look for processing errors in a survey dataset. It's a bit fiddly because I want to know about answer frequencies, and evaluate the shape of the value labels at the same time. So this script produces one frequency table per variable, revealing frequencies, unused labels, and values without value labels. This will hopefully be clearer when looking at the output from the script.

I would be grateful if you could point out some ways to make this more efficient:

It is not easy to help you without toy data, more simple code, and a clear explanation of input and output. Anyway, a first step is typically to profile your code in order determine the bottlenecks which consume time. See ?Rprof for the the Rprof()-function which provides profiling information.

This small example illustrates how to use it:
