Answer 1

[Azzi Abdelmalek]

You should replace / by ./

[Jorge]

after i replaced it by ./ i got this

Error using horzcat Dimensions of matrices being concatenated are not consistent.

Error in Firstmatlab1b (line 12) Results = [P', T_i', T_vw'];

[Azzi Abdelmalek]

Why you don't try to fix the problem? the error message says there is a problem with your concatenation.
