Hello, I am making app in Matlab App designer using .m file calculation. In .m file, I wrote polar plot, which have 101 digits, like this:

betta = @(r) asin(c_rinf(r) / w(r) + z * s / (2 * pi * r));
N = 100;
h = (r_2 - r_1) / N;
r = r_1:h:r_2;
thettar = zeros(size(r));
for i = 1:size(r,2)-1 
    for j = 1:i
        thettar(i+1) = thettar(i+1) + h * 0.5 * (1 / (r(j) * tan(betta(r(j)))) + 1 / (r(j+1) * tan(betta(r(j+1)))));
    end
end
polarplot(thettar, r)

After that, I have to write and show this in App Designer, but I don't realize how

I tried write like this, but it doesn't work

app.pax = polaraxes(app.UIAxes2);
polarplot(app.pax,thettar,r)

Hi, the first line of your app code ( app.pax = polaraxes(app.UIAxes2 ) is probably causing the trouble. It should be sufficient if you just make the plot in your designated axes within the app:

polarplot(app.UIAxes2,thettar,r)
