Function Documentation

interp() [1/2]

void interp	(	MatrixView	tia,
		ConstVectorView	itw,
		const 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

[out]	tia	Interpolated value.
[in]	itw	Interpolation weights.
[in]	a	The field to interpolate.(ArrayOfMatrix)
[in]	tc	The grid position for the column dimension.
