Proper classification of variables in parfor loop

Hi there I have a loop that I would like to run with parfor. A simplified version of the code is
parfor qx_index=1:Nsx*Nx
for qy_index=1:Nsx*Nx
chi(qx_index,qy_index,:)=function(other_variables,qx_index,qy_index)
end
end
When I run the code I get the following error:
Error: The variable chi in a parfor cannot be classified.
I cannot figure out why this doesn't work - help?

What you have above works fine for me (filling in a few of the blanks)...
chi = zeros(2,3);
parfor qx_index=1:2
for qy_index=1:3
chi(qx_index,qy_index,:)=afunction(qx_index,qy_index)
end
end
And
function z = afunction(y,x)
z = y*x;

There are a number of rules surrounding the functions you can use in a parfor loop. For example you cannot use nested functions or non-transparent functions like eval. Maybe your function does not meet these criteria?
