Behavior of fit for large S-parameters, specified as true or false.When true, the direct term in the fit is set to zero so that the rational fit F(S) tends to zero as S approaches infinity. When … This MATLAB function plots x- and y-coordinates using a base 10 logarithmic scale on the x-axis and the y-axis. log 10 b)]/m.
