Hi,

How do I suppress the error display in the command window. I know for warning display, I can use 'warning off all', .

I intend to use the errordlg only, so I do not want the error to be displayed in the command window.

Thanks.

I do not know of any way to suppress the display of an error() message.

However, you can use try/catch to catch the error. A caught error will
not print out anything.

Thank you Andy, Walter.

try /catch works.

However, to go a step further, when I use the try and catch , is there a way to invoke the try again.

For example,

try
statements
statements

catch
errordlg('error in your input')
end

Is there a way I can return the command back to the begining of the try statement, so that if the user now puts a valid input , then no error is generated.

I do not want to use the if statement, I just want the command to go back to the begining of the try statement, once an error is generated.

Thank you.

% something like this:

validInput = false;
userInput = input('Get user input here: ');

while ~validInput
try
process(userInput); % do whatever to the input
validInput = true;
catch
disp('Error in your input')
validInput = false;
end
end
