Plotting with nested for loops

I have resolved the issue with the following code:

clc, clear all
syms y
t=[0 pi 2*pi];
a=[5 10];
for k=1:length(a)
    for j=1:length(t)
        f=a(k)*sin(t(j)*y);
        fplot(y,f);hold on;
    end
end

Moslem - please clarify what you mean by failed to generate plot. Were any plots generated or none? Or just one? Or do you see an error?

I also wonder if you mean for y to be a "sym".

It gives only only figure. Yes, y is symbolic.

Original question retrieved from Google Cache:

I want to plot multiple figures using nested for loop, but failed to generate plot. I used the following code:

clc, clear all
syms y
t=[0 pi 2*pi];
a=[5 10];
for k=1:length(a)
    for j=1:length(t)
        f=a(k)*sin(t(j)*y);
        fplot(y,f);
    end
end

clc, clear all
syms y
t=[0 pi 2*pi];
a=[5 10];
for k=1:length(a)
    for j=1:length(t)
        f=a(k)*sin(t(j)*y);
        fplot(y,f);hold on;
    end
end

syms y
t=[0 pi 2*pi];
a=[5 10];
for k=1:length(a)
    for j=1:length(t)
        f=a(k)*sin(t(j)*y);
        figure             %only with this line
        fplot(y,f);
    end
end
