is2rc Convert inverse sine parameters to reflection coefficients K = is2rc(isin) isin: input inverse sine parameters. Needs to be an array real numbers k: output reflection coefficients corresponding to the reflection coefficients in input This function returns a vector of reflection coefficients from a vector of inverse sine parameters.output array has k(i) = sin(pi/2*isin(i)) rc2is rc2poly rc2ac rc2lar Parthe Pandit J.R.
