Creating another function by extension of an existing function

I have a function defined as

p = inline('(t>=0)&(t<1)','t');

with t being t=(-1:0.01:2);

I am trying to create another function

r(t)=t*p(t);

I keep getting errors saying ERROR using *, or mtimes not defined for the inline function, or that subscript indices must either be real or positive integers (when I transpose t that is).

Any help would be great. Im new to MATLAB.

[Walter Roberson]

p = @(t) (t>=0)&(t<1);
r = @(t) t .* p(t);

@Umair: Using inline is still supported for backward compatibility. But anonymous function are working for many years now, so prefer them.
