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

Input Arguments

collapse all

Log area ratio parameters, specified as a vector or as a matrix.

Data Types: single | double

Output Arguments

collapse all

List of reflection coefficients, returned as a vector or as a matrix, where k = -tanh(-g/2).
