whiten2D whitens cross-correlated time-series. Whitening filters are constructed by a fitting procedure to the corss-spectrum models provided. Note: The function assumes that the input model corresponds to the one-sided csd of the data to be whitened.
b = whiten2D(a, pl) [b1,b2] = whiten2D(a1, a2, pl) [b1,b2,...,bn] = whiten2D(a1,a2,...,an, pl);
