IntExt:

---------------------------------------------------------------------------
   One or two dimensional interpolation and extrapolation. If no outputs
   are given it will plot the interpolated/extrapolated values on the 
   same plot as the matrix a. x and y are assumed to be in order of
   minimum to maximum;
---------------------------------------------------------------------------
   Form:
   c = IntExp( a, x, xC, y, yC )
---------------------------------------------------------------------------
