IDWILT2 - 2D Inverse Discrete Wilson transform

Usage

f=idwilt2(c,g);
f=idwilt2(c,g1,g2);
f=idwilt2(c,g1,g2,Ls);

Input parameters

`c`	Array of coefficients.
`g, g1, g2`
	Window functions.
`Ls`	Size of reconstructed signal.

Output parameters

`f`	Output data, matrix.

Description

idwilt2(c,g) calculates a separable two dimensional inverse discrete Wilson transformation of the input coefficients c using the window g. The number of channels is deduced from the size of the coefficients c.

idwilt2(c,g1,g2) does the same using the window g1 along the first dimension, and window g2 along the second dimension.

idwilt2(c,g1,g2,Ls) cuts the signal to size Ls after the transformation is done.
