Why am I not able to define input types of Entry-Point Function in MATLAB Coder 3.3 (R2017a)?

My code has many inputs but the following message was shown in the Define Input Types step in the MATLAB Coder APP. I can define input types with the same code in R2013b.

1. >> coder

2. Add Stiff_Matrix_Gen

3. Click Next

In the Define Input Types step,

-------------------------------------

Function Stiff_Matrix_Gen does not have any input arguments. No input type definitions are required.

There is a bug in MATLAB Coder 3.3 (R2017a) in separated beginning lines of function code. This bug is fixed in R2017b. To work around this issue, combine beginning lines to contain input element in the first line.

For example,

In your code, it needs to be changed the three lines of function beginning.

Original:

-------------------------------------

function [Displacement_Results, Stress_Results, Restraint_Results, GlobalForce_Results] = ...

                  Stiff_Matrix_Gen ...

                  (CII_Element,CII_RIGID, ...

-------------------------------------

Modified:

-------------------------------------

function [Displacement_Results, Stress_Results, Restraint_Results, GlobalForce_Results] = Stiff_Matrix_Gen(CII_Element,CII_RIGID, ...
