Hi,
I have the following and I need to plot in time domain
fs = 40; t1 = 0:( 1/fs ):6; S2 = [ sin( 2*pi*5*t1( t1<=2 ) ), sin( 2*pi*10*t1( 2<t1<4 ) ),sin( 2*pi*15*t1( t1>4 ) ) ];
plot(t1,S2)
I am getting an error because t1 and S2 have different lengths?
How can I make then equal in length to plot S2 in time domain?
Thanks, I really appreciate your help

You can make them equal in the following way, but you might want to assign any other value instead of "0" which best match your purpose.
fs = 40;
t1 = 0:( 1/fs ):6; S2 = [ sin( 2*pi*5*t1( t1<=2 ) ), sin( 2*pi*10*t1( 2<t1<4 ) ),sin( 2*pi*15*t1( t1>4 ) ) ];
for i = length(t1)+ 1 : length(S2)
t1(:, i) = 0;
end
plot(t1,S2)
