It appears that "Xt" is superfluous, and tabtm is not the same size as  
tabdm or CSext.

... I've always used meshgrid or ndgrid to prepare inputs for interp2  
or similar functions.

A question for someone else is; Should the columns for "x" and the  
rows for "y" be identical for cubic(x,y,z,xi,yi) and/or for interp2?
