MATLAB: Error with surf function

Question

Hello,

I have the following data dimentions:

x = linspace(1,16,256)

y = linspace(1,16,256)

size( data ) = 256 x 16

I want to plot this as a 3D using surf function. I tried to use surf( x, y, data), but I got an error due to the length of the vectors. Does any body know how can I plot it proberly?

Answer 1

[m,n] = size(data) ; 
x = 1:n ; 
y = 1:m ; 
surf(x,y,data)

Also you can straight away use:

surf(data) ;
