How do i fix the negative and identical outputs i am getting under the FOR loop?

i am currently experiencing a challenge under my FOR loop, e.g my W_3 is generating similar and negative outputs while the inputs into the formular are all positive and this is happening throughout the loop.

"c", the speed of light, defined before the loop is overwritten in the loop. This causes the problem.

you are reusing the variable name c . looks like the speed of light before the loop but inside it is reassigned one of the matrix coefficients .

By the way do you have a good reason for approximating pi to only 3.142 ? if so you should comment .
