Function like "surf", but without interpolation?

I want to take a 16 x 16 array of data, and present it in 3D as an assembly of 16 x 16 cuboids, each having size "1" in the x and y directions, and a height proportional to the z value. "surf" almost does this, but it performs bilinear interpolation on the z values, and I want zeroth order hold. Also, "surf" would give a 15x15 surface, but I want a 16x16. I looked at some of the 3D bar charts but they don't seem to do what I want. Is there a function or option that I'm missing.
Thanks
