Add x and y Values to z data from excel file

4 views (last 30 days)
I have a 37x20 array in excel which corresponds to the magnitude of z value at each point. I would like to add the following x and y values to create a 3D matrix.
The resulting matrix would have coordinates of element 1 (0,0,(Value from z array))
Any help is greaty appreciated

It looks as though that would do exactly what you want.
For example, this:
z = rand(37,20); % Use Your ‘z’ Matrix Here
surf(x, y, z)
grid on
will plot it appropriately.

As always, my pleasure!
The plot3 function accepts only vectors, that all must be the same lengths. The surf function requires the third argument to be a matrix, although the first two can be either vectors or matrices (with the appropriate sizes).
