Using surf function to plot slices of a 3D matrix

Using "surf" function to plot slices of a 3D matrix

Hello

I have a 100x100x100 matrix called "A" and want to plot 2D slices of it to get a feel of where the global minima are (since there is no other way which I know of visualising it... is there?)

If I take a slice of the third component, eg. "surf(A(:,:,50))" it will plot it fine, but I cannot do this for the other two:

>>> surf(A(1,:,:))
? Error using ==> surf at 74
Z must be a matrix, not a scalar or vector.

Is there a simple workaround for this?

Thanks

Use surf(squeeze(A(1,:,). Squeeze will turn the 1 x 100 x 100 array into a 100 x 100 array.

Brilliant- thanks very much!
