Data is inferred as a variable size matrix, while its specified type is something else.

Let "x" and "y" be two variable-size vectors. now i have a variable named "z" which is defined as:
function z=func(input)
% some code here
% x,y are not input
z = sum(x.*y')/sum(x);
end
obviously "z" is a double variable. but when i send it as the output of the function i get this error:
Data 'z' (#32) is inferred as a variable size matrix, while its specified type is something else.
I guess Simulink assumes that "z" is variable-size too. I'm stuck at this point. any suggestions?

Before the final assignment to z, assign
z = 0;
This will tell Coder that the result is expected to be a scalar double.

Did you specifically mark a data type for the output signal for the MATLAB Function Block ?
