function Y=surrogate(x,M)

 Y=surrogate(x,M)

 Generates M amplitude adjusted phase shuffled surrogate time series from x. 
 Useufel for testing the underlying assumption that the null hypothesis consists
 of linear dynamics with possibly non-linear, monotonically increasing,
 measurement function.

 Required Input Parameters:

 x
       Nx1 vector of doubles

 M
       1x1 scalar specifying the number of surrogate time series to
       generate.

 Required Output Parameters:

 Y
       NxM vector of doubles
