HI, While executing this program

function erb = erlang_b(A,C)
% A= offered traffic in Erlangs.
% C= number of trunked channels.
num = A^C;
sum = 0
for k=0;C
  kfact = product(1:k);
  term  = (A^k)/kfact;
  sum   = sum+term;
end
Cfact = prod(1:C);
den   = Cfact*sum;
erb   = num/den;

Iam getting an Error i.e.,using erlang (line 4) Not enough input arguments. How can i resolve this

I notice an error in the script of your "erlang" function. The line

for k=0;C

should read:

for k=0:C

How are you calling this function? It has to be called with two inputs:

foo = erlang_b(pi,42)

The error you're getting is the one people get when they make the classic mistake of trying to run the function as a script (such as hitting the Run button).
