warning

Description

warning('string') prints the character string 'string' in a warning message.

warning(string_matrix) prints each element of the matrix string_matrix in a warning message.

'on' enables warning messages, warning messages do not interrupt script execution.

'off' disables warning messages, warning messages are ignored (neither displayed nor interrupting script execution).

'stop' enables warning messages and stops execution when a warning is encountered.

'query' gets state 'on', 'off' or 'stop'.

warning("on"), warning("off") and warning("stop") also affect hard-coded functions issuing warnings.

Examples

w_flag = warning("query"); // remembering the warning flag

warning('on')
warning('this is a warning')
warning('off')
warning('this is a warning')
warning('query')
warning('on')
// Example with a localized message
warning(msprintf(gettext("%s: Wrong number of input argument: %d expected.\n"),"myFunction",2));

// Setting warning stop
warning("stop")

try
    warning("this is a warning");
catch
    lasterror() // Warning message is considered an error
end

warning(w_flag); // resetting the warning flag
