Change value at axis ?

Hi,

I have a 81x200 double which i want to plot with surf(). Since my matrix is 80 column wide the values at x axis is from 0 to 81. In practice, i would like the xaxis to say -40 to 40 but with the same surf plot just changing the values shown on x-axis in the plot.

If i use axis ([- 40 40 0 200 ]) i will get no values from -40 to 0...

Can someone please help me!

Regards

surf(X,Y,Z,C)

allows you to specify the x and y range of your data as the first two arguments (there is a version without the C too if you don't have colour data to explicitly define).
