What do i do to make f time g where f and g are inline function?
Thank for your answer.

If you want a single inline function you evaluate to obtain the product,
it's kind of messy.

f = inline('sin(x)', 'x');
g = inline('cos(x)', 'x');
h = inline('feval(f, x).*feval(g, x)', 'x', 'f', 'g');
t1 = feval(h, 1:10, f, g)

Of course, if you need to evaluate the product once you could write:

f = inline('sin(x)', 'x');
g = inline('cos(x)', 'x');
t2 = feval(f, 1:10) .* feval(g, 1:10)

If you're using MATLAB 7.0 or later, use anonymous functions instead.

f = @(x) sin(x);
g = @(x) cos(x);
h = @(x) f(x).*g(x);
t3 = h(1:10)

.... could read

f=@sin;
g=@cos;
h=@(x) f(x).*g(x);
h(1:10)

just a thought
