how to run a function file in for loop

Dear all,

I am new to matlab. I want to run a function file in for-loop in different m-file.

suppose my function file is

function p =RCfilter(fs)
fs = 15;
-----
-----
p = sincOp.*cosOp;
end 

i want to call this function in another file in for loop:

for l=1:1:4
    Channel=Channel+j*alpha(l)*a(:,l)'*RCfilter(Ts - ndelay(l))-------how to call function RCfilter here;

end  

please help!!

for l=1:1:4    
    Channel=Channel+j*alpha(l)*a(:,l)'*RCfilter(Ts - ndelay(l));
