Hi,

I am getting error ,"Undefined function 'setPlotProp' for input arguments of type 'struct'".

I am attaching code below:

x=42.63;
y= tand(x)^2;
ZL_1=40;
ZL_2=60;
ZL_3=80;
ZL_4=100;
Zv=30:10:150;
Z1_1=(sqrt(ZL_1*[Zv.*(1+y)-ZL_1]))./tand(x);
Z1_2=(sqrt(ZL_2*[Zv.*(1+y)-ZL_2]))./tand(x);
Z1_3=(sqrt(ZL_3*[Zv.*(1+y)-ZL_3]))./tand(x);
Z1_4=(sqrt(ZL_4*[Zv.*(1+y)-ZL_4]))./tand(x);
plot(Zv, Z1_1);
hold on;
plot(Zv, Z1_2);
hold on;
plot(Zv, Z1_3);
hold on;
plot(Zv, Z1_4);
hold on;
