# MATLAB: Matrix dimensions must agree.

dimensionmatrix

Hello everyone, can you please help me with this problem? I currently in my project's for Iterative Method. But I can't run the coding because of this problem.
P=(Lamda-beta)./(gamma*2);
Attached below is my full coding, can you guys help me?
