Syntax

Function call

abcd_params = y2abcd(y_params) — converts Y-parameters y_params in ABCD, the parameters are abcd_params.

Arguments

Input arguments

# y_params — 2N-port Y-parameters

+ 2N×2N×M array of complex numbers

Details

2N-port Y-parameters specified as an array of complex numbers of size on on , where represents the number of frequency points of the 2N-port Y-parameters.

Output arguments

# abcd_params — 2N-port ABCD-parameters

+ 2N×2N×M array of complex numbers

Details

2N-port ABCD parameters returned as an array of complex numbers of the size on on , where represents the number of frequency points of 2N-port ABCDparameters.

The output matrices of the ABCDparameters have different submatrices , , and :
