Code generation requires variable 'ac' to be fully defined before subscripting it. Code generation requires variable 'an' to be fully defined before subscripting it. Code generation requires variable 'A11' to be fully defined before subscripting it.

Near the top of the code, you need to add
ac = zeros(4,1);
an = zeros(4,1);
A1 = zeros(size(L));
Darshan Ramakant Bhat
Like Walter suggested you need to fully difine variables size before accessing it.
You can use %#codegen pragma at the beginning of your function to get all such issues highlighted.
I could modify the function a bit and and get it working with codegen. Please do a diff with the modified code and your code to check what exactly is changed. You can tweek it a little bit to suite your application.
Please use the attached files.
Hope this will be helpful
