Actually using numpy you'll be much faster in this case:

Personally I use winpython: https://winpython.github.io/
That have all the scientific packages already available.
It can run without being installed and uses spyder as an IDE (for small
projects it's ok).
And, I can import pygame (even though I have not tested if everything works)
in python 3.11

You can also have a look at www.scipy.org where you can find some packages used
for scientific programming like numpy, scipy, matplotlib.
The last one is a graphic package that may be useful to make some initial plots.

Keep also in mind that numpy is quite different from Matlab.
In Matlab every vaiable is a matrix of at least 2 dimensions.
This is not the case of numpy (and is not the case in Fortran too).
every array can have a different number of dimensions. The transposition of an
array with just 1 dimension
Every array in numpy has a number of dimensions,
"np.array" is a function that can create an array numpy given a list.
when you write
vector_1 = np.array([1,2,1])
you are passing a list of number to thet function array that will create a 1D
array.
As you are showing:
vector_1.shape
will retur

Use the vectorization given by numpy:
ytemp = (ydata - ydata[0]) * 0.001

I work in research and mainly use Fortran and Python.
I haven't had any problem with the python indentation. I like it, I find it
simple and easy.
Well, sometimes I may forget to close an IF block with an ENDIF, in Fortran, so
used I am on ending a block just decreasing the indentation, not a
35 matches
