TRY  TRY-CATCH Try and Catch Statement


Usage
 
 The try and catch statements are used for error handling
 and control.  A concept present in C++, the try and catch
 statements are used with two statement blocks as follows
 
    try
      statements_1
    catch
      statements_2
    end
 
 The meaning of this construction is: try to execute statements_1,
 and if any errors occur during the execution, then execute the
 code in statements_2.  An error can either be a FreeMat generated
 error (such as a syntax error in the use of a built in function), or
 an error raised with the error command.
