Hi, I am using "gamultiobj" to solve my problem. I, however, have no idea why the error message occurred
??? Error using ==> mtimes Inner matrix dimensions must agree.
Error in ==> col_mop>@(x)x'*(B'*B)*x at 50 fun1 = @(x) x'*(B'*B)*x;
My objective function is coded as follows
fun1 = @(x) x'*(B'*B)*x; fun2 = @(x) x'*x; bifun = @(x) [fun1(x) fun2(x)];
The dimension of B'*B is m so x is an m-by-1 vector. The syntax for gamultiobj is
X = gamultiobj(FITNESSFCN,NVARS,A,b,Aeq,beq,LB,UB,options)
I have properly input the number of decision variables (NVARS) as m but the error message shows. I also check the dimensions using the command "whos" which showed what I wanted. Is there anything wrong?
Thanks in advance.
(look at Matt Fig answer on that question)
