Spline Interpolation

[JohnRudnicki]

Is there a way to interpolate values of a matrix that is not square? I.e.
cspline(Mxy,Mz)and interp(vs,Mxy,Mz,X)
where Mz is not square?

Matlab has such a function but is there a way to do it without inserting a Matlab component (which I havent tried before).

Thanks.

One way is to interpolate the matrix in one direction to create a new column (or row), and then interpolate the column (or row).

Yes, See my cubic splines worksheet for the functions.

Tom,

Thanks. It took me a while to find it, but it worked like a charm and studying it was a real education.

YES, use Valery rectangular spline.
