HowTo 'IFError' and skip

How do identify an error in order that I can skip and run alternative script.

I want to

    if fprintf('\t%s\n',TPin{1,2}{:}) iserror("??? Cell contents reference from a non-cell array object.")

do A;

else

do B;

90% of the time no error will occur, so would I be better writing;

do fprintf('\t%s\n',TPin{1,2}{:});
iserror goto do alternative;

In any case how do I pick up the error and perform a switch in task.

You want to use a "try ... catch" construct:

   >> doc try

Thanks have just read,

Just to simplify for myself to prove vague understanding.

'try' runs code/function if successful no action taken and resumes outside 'end'

'catch' errors within 'try' caught and alternative script or message can be executed.

Thanks both of you, just what the doctor ordered.
