Hello on the file that is attached I want to substitute a variable called My by the result of momento so then all the operations where My is used start to use the output of momento. I tried subs(My,momento) but it didnt work. All the operations still have My. Thank you.

@ Nadia Bica: to upload a file you need to click the paperclip button, and then push both buttons: Choose file and Attach file.

The subs function needs three arguments. You have to tell subs the expression you want to substitute your variables in. That is the part you did not state in your subs call.
For example (assuming that you want to substitute ‘momento’ for ‘My’ in a function I call ‘F’ here):
syms x y My
F = x + y + My;
momento = x*y;
F = subs(F, My, momento)
produces:
F =
x + y + x*y
