Plot 3D array

Hi,

I have a cell array of 1x10 (variable k) where each of the 10 arrays are matrices of 80x31.

Now I want to make a 3D plot with x=1:80, y=k=1:10 and z my cell array.

I have tried with

surf(1:80,k,mycell{1:length(k)}(1:80,1))

but it does not work.

Any help will be very much appreciated.
