Function Documentation

Matrix interp	(	ConstVectorView	itw,
		ArrayOfMatrix	a,
		const GridPos &	tc
	)

Red 1D Interpolate.

This is a slight modifiaction of Stefan's code to do 1_D interpolation to get a Matrix from an array of Matrices

The dimension of itw must be consistent with the dimension of the interpolation (2^n).

Parameters:

	itw	Interpolation weights.
	a	The field to interpolate.(ArrayOfMatrix)
	tc	The grid position for the column dimension.

Returns:

Interpolated value.
