How can i plot a 3d graph using a matrix?

I want to plot a 3D graph using a matrix and i want matrix values to be on Z axis and define values on X & Y axes separately.

Can you help me please?

Thanks

What kind of graph? What you describe could be for a surface graph,

surf(X, Y, Z)

or for a mesh(), or (with more work) a 3D line plot using plot3() (but then you have to say what should be connected to what)

I want to plot 3d bar graphs dear Walter.

You can use bar3() but it does not permit passing in Y values. You would have to modify the barseries returned by bar3, especially the coordinates in the patches that are children of the barseries.

Possibly there is a MATLAB File Exchange (FEX) contribution that does this work.
