Function Declaration Compatibililty with Pre-R14 M-Files
As of Release 14, the function definition line in a function M-file no longer requires
commas separating output variables. However, because this syntax is not compatible
with earlier releases, you should always include the comma separators when writing an
M-file function that you intend to run on releases both earlier and later than Release 14.
Compatibility Considerations
See Comma Separators Not Required in Function Declaration in the Release 14 release
notes.
