MATLAB: Detect errors on GUI

editerrorguiguidetext;

Hello, I want to make an .exe program using guide. I designed everything.

I want to detect the errors on my code because of the input values. For example for the input value if I input an absurd value (high or low) it gives "Index exceeds matrix dimensions" error on the command window. Now i can see that. But when i create .exe how can I understand the error? Is it possible?

Or, if I get an any kind of error, how can i write "NaN" or "0" to the results section (edit texts).

Thank in advance.

You should be coding in such a way that you never get those index errors: your code should be testing the user input range or calculated range before doing the indexing.

In the meantime, you should be putting try/catch clauses in your code to detect and display errors that do occur.

try
   output = myfunction();
catch ME
   output = nan;
end

This ability is not available in Datafeed Toolbox 2.1 (R2007b).

To work around this issue, you should put the calls in a loop within a TRY/CATCH block. This way, if an error occurs during execution of any of the statements, the error is captured, while the statements between the catch and end are executed. The syntax for a try/catch loop might look something like the following

for index = 1:10
      try
          results = fetch(connect,'S5FINL Index','History','INDX_MEMBERS');
      catch 
          results = NaN;
      end
end

The MATLAB documentation describes how to use TRY/CATCH blocks. There is also a section in Tech Note 1207 on our support website that describes the TRY/CATCH block.

MATLAB: Is there a way to catch errors with out using try catch statements

No, writing TRY-CATCH blocks is not time-consuming. It is required to catch errors and of course you cannot catch all problems automagically.

A reliable program requires an error handling and at least including the main function should be the absolut minimum.
