Nested functions are not supported.
Function 'arduino.m' (#44.43600.43622), line 1026, column 22:
"validateBoardPortMatch"
Launch diagnostic report.

Which release of MATLAB are you using? The latest version of MATLAB supports code generation for nested functions with some limitations. Please go through this link for more information. Additionally, go through this link for determining whether your function is suitable for code generation.
You could also try using 'level-2 MATLAB S-Function'. You can find more info on this here .
