Suppose that you have a signal Y (Y can be a time series, a parametric surface or a volumetric data series) corrupted by a Gaussian noise with unknown variance. It is often of interest to know more about this variance. EVAR(Y) thus returns an estimated variance of the additive noise.EVAR provides...

The function essentially simulates the colored noise which essentially is a correlated process and unlike the white noise does not have flat PSD. Although white noise is a realistic process color noise seems more practical and hence it requires correct modeling and simulation. The simulation here...
