filter, decay, delayed versions

Hello everyone,
I need advice on a simple query.
I need a FIR filter which has decay time specified by me.
The filter coefficients will decay either exponentially or any profile I want.
The filter will basically add delayed versions of my signal which is randn(1,1000).
How can I do this in matlab?
Cheers
P

Perhaps something like this:
B = [1,3,2,4,5,6,4,3]; % Or "any profile you want"
B = B / sum(B); % For example
A = 1;
x = rand(1, 1000);
y = filter(B, A, x);
