Hi all, first time user and I have only started to use matlab recently.
I need help with making matrix's dimensions agree.
I am using the following formula: E = -(G*M/R^2)*(Y1/R) where R = sqrt(Y1^.2 +Y2.^2)
the following occurs when i try and find E
??? Error using ==> mldivide
Matrix dimensions must agree.
Error in ==> Eastward_easy at 4
E = -(G*M/R.^2)
How do I get the matrix's to agree?
