surf plot: Z must be a matrix, not a scalar or vector

Hi guys,

I am having the error as titled. My problem is a bit different from the others. I have a matrix Res = 33x201x181 which was generated from 3 different parameters. A = 1x33, B = 1x201 and C = 1x181. I want to do a surface plot like

surf(B,C,Res(1,:,:))

But it kept coming with the error of Z must be a matrix. I don't really understand why Res(1,:,:) wasn't recognize as matrix. Thank you for you help.

Show us the calculations of Res.....

surf(B, C, squeeze(Res(1,:,:)))
