    % SEMILOGX Semi-log scale plot for FRDs.
%    SEMILOGX(...) is the same as PLOT(...), except a
%    logarithmic (base 10) scale is used for the X-axis.
%  
%EXAMPLE: Generate a frequency response of a first order system and plot it.
%  
% x = tf(1,[1 2]);
% om = logspace(-2,2,80);
% xg = frd(x,om);
% semilogx(abs(xg))
