@Riyadh next time when posting a question better is to attach your script file instead of pasting 400 lines of code ! I formatted your code today.

you are setting an element, a(t) to be equal to your entire matrix a.

Not sure what you are trying to do, please reformat your question so it's easier to look at.

i am setting element a(t) to save the results i guess i figured the answer by adding the loop t=1:100; . i am trying to simulate mathimaticlly a tram by moving from between two stations (electriclly) first i clculate the motion resistances then F and then comes breaking process .

thanks.
