rc2lar

Convert reflection coefficients to log area ratio parameters

Syntax

g = rc2lar(k)

g = rc2lar(k) returns a vector of log area ratio parameters g from a vector of reflection coefficients k.

Define a vector, k, of reflection coefficients and compute the log area ratio parameters.

k = [0.3090 0.9801 0.0031 0.0082 -0.0082];
g = rc2lar(k)

g = 1×5

    0.6389    4.6002    0.0062    0.0164   -0.0164
