You might have to modify M-file programs that expect the previous behavior from

Warning Generated by try-catch
To accommodate future changes in the MATLAB error-handling capabilities, there is a
new restriction to the syntax of the try-catch block. When the first MATLAB statement
that follows the try keyword consists of just a single term (e.g., A as opposed to A+B)
occurring on the same line as the try, then that statement and the try keyword should
be separated by a comma. For example, the line
try A
should be written as either
try, A
or on two lines as
try
A
This affects only single-term statements. For example, the following statement continues
to be valid:
try A+B
The same holds true for the catch keyword and a single-term statement following the
keyword on the same line. A valid try-catch statement of this type should be composed
as follows:
try, A, catch, B, end
If you omit the commas following try and/or catch, your code will continue to operate
correctly. However, MATLAB will issue a warning:
