Not enough input arguments

Hi all,
the following code yields me this error:
Not enough input arguments in line 1.
this is the code:
function [Re] = varmom(m,t,rf);
epsilon = zero(m,t,rf);
r = zeros(m,t);
for m=1:M;
epsilon(m,:,:) = mvnrnd(0, [0.006,-0.0051],t);
end
for m =1:M
r(m,1)=0.227+ epsilon(m,1,1)
for i = 1:T-1;
r(m,i+1) = 0.027 + epsilon(m,i+1,1);
end
end
%create excess return out of log excess return
Re = rf*exp(r)-rf;
Where m is #simulations, t is timehorizon and rf is a constant riskfree rate.
Something should be wrong in line one but I don't know how to fix it.
Any suggestions?
Cheers.

How do you call this function?
You need input arguments when running it (you can't press F5 or something similar).
You could also define default arguments to be used if no input is provided:
if nargin < 3
rf = ..
if nargin < 2
t = ..
if nargin < 1
m = ..
end
end
end
Hope it helps =)

I just noticed zeros(M,T,rf). As rf is not an integer, this is not good. Which dimension do you want it to have?

Use lower case m, or some other letter that can't be mixed with upper case M, as indices in your for-loops, and you'll get there =)
if nargin < 3
rf = 1.06
if nargin < 2
T = 20
if nargin < 1
M = 1000
end
end
end
epsilon = zeros(M,T,rf);
r = zeros(M,T);
for ii=1:M;
epsilon(ii,:,:) = mvnrnd(0, [0.006],T);
end
for jj =1:M
r(jj,1)=0.227+ epsilon(jj,1,1)
for kk = 1:T-1;
r(jj,kk+1) = 0.027 + epsilon(jj,kk+1,1);
end
end
%create excess return out of log excess return
Re = rf*exp(r)-rf;

I'm an electrical engineer and haven't got a clue what you're asking for, sorry about that... Glad I could help out with the programming part though =)
