Hi all,
I have two vectors and a matrix that I would like to plot in 3D (as surfaces). I have seen that there is a command called surf() to do so. Now, my variables are two vectors, say k1 and k2 of length (1x741) and a matrix, say omega, of dimension (12x741). When I perform:
[X,Y]=meshgrid(k1,k2)
my new vectors X and Y, are, of course 741x741. My problem is: is there a way to transform the 12x741 matrix in, say, a matrix Z so that I can perform
surf(X,Y,Z)
without dimensionality errors?
Thank you

You can use interp2, imresize to resize your desired matrices into required dimensions.
Let Omega be your matrix of size 12*741.
Z = imresize(Omega,[741 741]) ;
Now you can use surf.

@KSSV thank you for your reply. However, I might have posed the question in the wrong way. In particular I would like 12 surfaces to appear. The matrix Omega is a 12x741 since it contains 12 curves. With imresize the surface plot is just one
