how to perform time scaling( expansion and compression ) on continuous and bounded signal?

a matlab code to perform time scaling( expansion and compression ) on continuous and bounded signal?

well to give a proper answer, we need more information about what you are trying to do. But in the general sense, a signal in matlab is usually just a representated vector, and the time information is usually a separate vector. e.g.

t=0:0.001:10;
signal = sin( 10 * 2 * pi * t);
plot(t, signal);

So to do scaling on the time, you don't have to touch the signal vector, just scale the time vector. e.g. tscale=t*2, or tscale=t/2 or whatever you want.

Answer 1

t=0:0.001:10;

signal = sin( 10 * 2 * pi * t);

plot(t, signal);

Answer 2

t=0:0.001:10;

signal = sin( 10 * 2 * pi * t);

plot(t, signal);
