lar2rc

Convert log area ratio parameters to reflection coefficients

Syntax

k = lar2rc(g)

k = lar2rc(g) returns a vector of reflection coefficients k from a vector of log area ratio parameters g.

Given a vector, g, of log area ratio parameters, determine the corresponding vector of reflection coefficients.

g = [0.6389 4.5989 0.0063 0.0163 -0.0163];
k = lar2rc(g)

k = 1×5
