Hello,
I am trying to multiply a continous periodic sine wave to that of a rectangular pulse, But I see the error that the matrix dimensions must agree, Is it possible to multiply two different signals in MATLAB? can you please help me with one example code? or may be the commands that could be helpful.
x = 0:0.05:6;
y = sin(x)
subplot(3,1,1)
plot(x,y)
t1 = 0:0.05:1;
t2 = 1:0.05:2;
t3 = 2:0.05:3;
t4 = 3:0.05:4;
t5 = 4:0.05:5;
t6 = 5:0.05:6;
t=[t1 t2 t3 t4 t5 t6];
x1 = ones(size(t1));
x2 = zeros(size(t2));
x3 = ones(size(t3));
x4 = ones(size(t4));
x5 = zeros(size(t5));
x6 = ones(size(t6));
xs = [x1 x2 x3 x4 x5 x6]
subplot(3,1,2)
plot(t,xs);
ylim([-0.5 6])
%
% mul = xs.*y;
% subplot(3,1,3)
% plot(t,mul)
% ylim([-0.5 6])
The present code is this
Thank you

You made a mistake in defining t2...t6:
x = 0:0.05:6;
y = sin(x);
subplot(3,1,1)
plot(x,y)
t1 = 0:0.05:1;
t2 = 1.05:0.05:2;
t3 = 2.05:0.05:3;
t4 = 3.05:0.05:4;
t5 = 4.05:0.05:5;
t6 = 5.05:0.05:6;
t=[t1 t2 t3 t4 t5 t6];
x1 = ones(size(t1));
x2 = zeros(size(t2));
x3 = ones(size(t3));
x4 = ones(size(t4));
x5 = zeros(size(t5));
x6 = ones(size(t6));
xs = [x1 x2 x3 x4 x5 x6];
subplot(3,1,2)
plot(t,xs);
ylim([-0.5 6])
mul = xs.*y;
subplot(3,1,3)
plot(t,mul)
ylim([-0.5 6])
