== Error messages == | |||
When you encounter an error condition, call the function {{codeline|error}} | |||
(or {{codeline|print_usage}}). The {{codeline|error}} and {{codeline|print_usage}} functions | |||
do not return. It is customary to prefix the error message | |||
with the name of the function that generated it. For example: | |||
<pre>error ("my_cool_function: input A must be a matrix");</pre> | |||
Octave has several functions that produce error messages according | |||
to the Octave guidelines. Consider using {{codeline|inputParser}} | |||
and {{codeline|validateattributes}}. | |||
