I want to create function handle that satisfies the following discrete sinusoid
n = -10:1:10;
x = sin(3*pi*n);
x(n<0) = 0 ;
x(n>5) = 0 ;
stem(n,x)

my go was
x = @(t) sin(3*pi*n)
However, I was not able to include the given conditions, i.e. x(n<0) = 0 and x(n>5) = 0 in the fuction handle

@Romio: in your question you use x for a numeric vector, but in your comment you use x for a function handle. This is confusing.

fun = @(t) sin(3*pi*n) .* (n>=0 & n<=5);
