The issue was that I hadn't declared an else/elseif in the if statement so Simulink didn't know what to do if the statement wasn't applying.

Hello all,
I have been trying to work out how to implement a vector of any size (1xn) with MATLAB functions in Simulink. For the purposes of this question, let's take a simple test model found in the attached image.
In the first MATLAB function, I have the following simple code:
function y = fcn(u)
if(u == 1)
a = zeros(1,6);
y = a;
end
end
In the second MATLAB function, I have the following code:
function k = fcn(u1)
if(u1(1) == 0)
k = 2;
end
end
Based on answers on relative previous questions in the forum, I have the following settings regarding the variables in both MATLAB function:
However, I get the following errors when I try to run the model:
Output argument 'k' is not assigned on some execution paths.
Function 'MATLAB Function1' (#2181.9.10), line 1, column 10:
"k"
Launch diagnostic report.
Component:MATLAB Function | Category:Coder error
Errors occurred during parsing of MATLAB function 'untitled/MATLAB Function1'

Output argument 'y' is not assigned on some execution paths.

Any ideas what I am doing wrong?
Thanks,
