noisegen2D generates colored noise from withe noise with a given cross spectrum. The coloring filter is constructed by a fitting procedure to the models provided. If no model is provided an error is prompted. The cross-spectral matrix is assumed to be frequency by frequency of the type:
/ csd11(f) csd12(f) \ CSD(f) = | | \ csd21(f) csd22(f) /
Note: The function output colored noise data with one-sided cross spectral density corresponding to the model provided.
b = noisegen2D(a, pl) [b1,b2] = noisegen2D(a1, a2, pl) [b1,b2,...,bn] = noisegen2D(a1,a2,...,an, pl);
