Hi,
I am unable to hold both stepplot and pzplot in this loop despite trying different answers in the forum.
Can someone help?
syms g s z w
w1 = 4
z1 = 0.5
getAllInfo(w1,z1)
w2 = 4
z2 = 0.3
getAllInfo(w2,z2)
w3 = 2
z3 = 0.5
getAllInfo(w3,z3)
w4 = 2
z4 = 0.3
getAllInfo(w4,z4)
function getAllInfo(w,z)
num = [w^2]
den = [1 2*z*w w^2]
G = tf(num, den)
stepplot(G);
ax1 = axes ;
hold(ax1,'on')
figure()
pzplot(G);
ax2 = axes ;
hold(ax2,'on')
end

Hi,
One solution might be creating axes outside the function and pass them as parameters to the function.
Use hold on and plot on required axes.
For instance
f1 = figure;
ax1 = axes(f1) ;
f2 = figure;
ax2 = axes(f2) ;
hold(ax1,'on');
hold(ax2,'on');
syms g s z w
w1 = 4
z1 = 0.5
getAllInfo(w1,z1,ax1,ax2)
function getAllInfo(w,z,ax1,ax2)
num = [w^2]
den = [1 2*z*w w^2]
G = tf(num, den)
stepplot(ax1,G);
pzplot(ax2,G);
end
This will create all stepplots in one figure and pzplots in other one.
Hope this helps!
