Subscripted assignment dimension mismatch error

1 view (last 30 days)
I'm having this error and unfortunately I can't seem to see what's wrong in it. Here are the dimension of the variables:
ki=150, a=0, b=2, hx=0.1818, c=0, d=5, hy=0.3125, pi=150x1 double
Thank you in advance!
figure(1)
U(1:ki,1:ki)=pi;
[X,Y]=meshgrid(a:hx:b,c:hy:d);
surf(X,Y,U');

When you write:
U(1:ki,1:ki)=pi;
You're trying to put a 150x1 into a 150x150...Maybe what you intended was:
U(1:ki,1:ki)=repmat(pi,1,150);
It's a little unclear what you're after, but if you want to assign to a 150x150 you should probably give it a 150x150

It's the first time I'm computing something like that, but at least I can see a graph. Thank you!
