I have a matrix similar to this:

Code 1

I run a loop and append data into a list. I failed to convert the list to a data frame in the loop and only able to fix that in a later step and turn every 3 columns into a new row. I was wondering if I can transform a list into a data frame during the loop session.

I have a problem about not accessing GPU in PyCharm and I use NVIDIA as GPU.

Here is my code snippet which is shown below.

I am attempting to add another checkbox to this program but for some reason it will not display when I run the program. Only the check box for the blue pill displays. I have attempted to add a couple things or change the way the program is structured, but nothing I have done so far has helped.

Code Below:

So I compiled and ran the following C program:

I am trying to get the Coriolis matrix for my robot (need the matrix explicitly for the controller) based on the following approach which I have found online:
