Convert autocorrelation sequence to reflection coefficients
[k,r0] = ac2rc(r)
[k,r0] = ac2rc(r) finds the reflection
k, corresponding to the autocorrelation sequence
r0 contains the zero-lag autocorrelation.
r is a matrix where the columns are separate channels of
r0 contains the zero-lag autocorrelation
coefficient for each channel. These reflection coefficients can be used to specify the
lattice prediction filter that produces a sequence with approximately the same
autocorrelation sequence as the given sequence
You can apply this function to real or complex data.
