How to use the zplane command in app designer

30 views (last 30 days)
I have to make a pole-zero plot on a Matlab app without a pop-up
t = -pi:0.01:pi;
num1 = poly(zer);
dem1 = poly(pol);
num = flip(num1);
dem = flip(dem1);
[h,w] = freqz(num,dem,t);
% h = abs(h);
plot(app.UIAxes2, w,h);
xlim(app.UIAxes2,[-pi pi]);
% zplane(num1,dem1)
title('Pole-Zero plot')

I dont think zplane() has a syntax to pass in handle to target axes. Instead plot zeros and poles separately using plot function which can be used in plot(app.UIAxes,...) syntax.
