multiplicar señales

Buenas!
Tengo que hacer unas practicas en matlab y necesito hacer lo siguiente:
1. A causal signal is a signal is zero for all time values less than 0. It is represented mathematically as
Y(t)= x(t) if t>=0
0 if t<0
It can be obtained by multiplying the signal by the unit ramp signal which is mathematically represented as
u(t)= 1 if t>=0
0 if t<0
This can be implemented in MATLAB as
u=(t>0);
Write a MATLAB script to plot a causal signal y(t) created by multiplying x(t) with u(t) and plot the three signals on the one graph.
tengo todo hecho, solo falta hacer u(t)*x(t), que no se como hacerlo, he estado buscando por internet y tal, y la verdad esque no hay mucha informacion.
Gracias de antemano!
