You have to write a function and include the first line inside the code. — NKN, Sep 03 '14 at 07:01

First call the function and store the two outputs, then run your extra function unit32 (what does it do, by the way?) on the first output only:

[vMsgOriginal, errMsg] = Gateway_test_app(2);
vMsg = unit32(vMsgOriginal);

This assumes that you don't want to process your new string output through your unit32 function.
