Output type definition for extrinsic function (polyxpoly) in Simulink

Hi,
I'm needing to use an extrinsic function in an embedded matlab block in simulink (polyxpoly).
My problem is that the output of this function is an x by 2 array where x varies. I am therefore unable to define the output type without getting an mxarray error.
How can I make use of this function in a simulink matlab function block?

Since the Embedded MATLAB block uses static memory allocation, it cannot handle variables that change size dynamically. What you can do is declare your output as variable-sized while specifying an upper bound for the size.
function y = myfun(x)
coder.varsize('y', [1024 2]); %x must never exceed 1024
coder.extrinsic('polyxpoly');
y = zeros(x, 2); %pre-declare the type and size of y
y = polyxpoly(x, other_args, ...);

Hi,
During code generation, I keep getting the error -
' CODER.VARSIZE is not applicable to 'mxArray '. '
Has anyone encountered this/ know a way around this?
Here is a screenshot of the code generation error report :
