result = gammain(s_params,z0,zl)
result = gammain(s_params,z0,zl) calculates the input reflection coefficient of a 2-port network. s_params is a complex 2-by-2-by-m array, representing m 2-port S-parameters. z0 is the reference impedance Z0; its default value is 50 ohms. zl is the load impedance Zl; its default value is also 50 ohms. result is an m-element complex vector.
