Hello, I have this code, but i can't plot the variable Pw because it says "Error using plot,A numeric or double convertible argument is expected" but 've tried with ezplot, and stems and any of them fix the problem, what i have to do to plot Pw?
t=1e3:100:10e3;
syms p;
%x=-1510:1:1610;
%y=((x.^2)/(41)-1000);
%y1=y*-10;
w1=2e3;
w2=8e3;
A=10;
B=20;
g=parabola1;
%g1=EDFA;
z=100e-6;
%figure(3)
%plot(parabola1)
%fprintf(parabola1);
%axis([1300 1800 0 10e3])
figure(1)
f(t)=A*sin(w1*t)+B*cos(w2*t);
Pi=f(t);
plot(Pi)
figure(2)
%pione=EDFASinglePassGain_Analytical(Pi);
%stem(pione)
Pw=Pi.^(g*z);
plot(Pw)
%figure(4)
%Pw1=Pi.^g1*z;
%plot(Pw1)

Old enough releases cannot ezplot symbolic and need to fplot instead .

At the moment it does not make sense to me that you would get that error message. Can you save Pw into a .mat and attach that?
