The SPLINETABLE function

SPLINETABLE is a variation of the TABLE input function, and uses the same table format.

name = SPLINETABLE ( 'filename' )        

SPLINETABLE causes the data to be interpolated using cubic splines.  The interpolating functions are constructed so that the interpolated value and its first and second derivatives are all continuous across table grid positions.  A condition of zero curvature is applied at the table edges.

Only tables of one or two dimensions are currently supported.
