You need to have a license for Financial Toolbox and you need to install it
in order to use functions from that toolbox. Contact the person who's
responsible for your license and ask them if you're licensed for the
Financial Toolbox. To check if it is installed, use the VER function.

I am looking for a function that will enable me to test whether a
time series rises or falls after a moving average crossover.

Thanks

Ok you want the script for the movavg.
You can try with this

"
function a = movavg(x,n)
if nargin<4, error('Not enough input.'), end
if n<=0, error('n must be positive.'), end
if (n~=floor(n)), error('n must be an integer.'), end
if min(size(x))==1,
x=x(:); % forces x to be a column vector
end
[p,q]=size(x);
b = (x(1:p,1));
r = (x(1:p,2));
if n>p,
error('n must not be greater than the length of x.')
end

a=[];
for row=1:(p-n+1),
a=[a; mean(r(row:(row+n-1),:))];
end
[i,z]=size(a);
"
This is the scripts for moving average, where x is the matrix of data
l is the elements of average (l >= 2), q or r are the column for
wich i made the movavg. The result is a, for column a his size i
< p (size row of x).
To choose the column of the matrix you must change in ( b=
(x(1:p,1)) the number of column, as example
d = (x(1:p,3))
