Complex Function Grapher

This script contains a function that allows you to easily sort a list by multiple columns in ascending and descending order similar in function to the ORDER BY clause in SQL.

This script contains a function to use the timeit module from a script, creating a nice overview of the runtimes of one or more code snippets. All command line flags that the timeit module accepts can be used. The output can easily be customized.

This function makes it easier to use the timeit module from the interactive interpreter. You should just specify function with (optional) arguments to run, optional number of runs, and optional name of module (which if not specified defaults to the name of the function).

I was not able to get the peaks from my experimentally obtained data because of its random nature. As a result the findpeaks() defined in Matlab library was not giving results as expected. Hence I made a code which will help findpeaks() help detect the peaks more accurately.It basically averages...

This function generates Walsh Codes. The difference between this function and other functions available to generate walsh code is :1. you can call this function directly in your script, you will have to pass only the value of 'a' (length of code is 2 ^ a)2. this function can return you both the...
