MATLAB: Plotting with nested for loops

Question

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

Answer 1

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
