Either returns or sets the last error message. The general syntax for its use is either
msg = lasterr
which returns the last error message that occured, or
lasterr(msg)
which sets the contents of the last error message.
Here is an example of using the error
function to set the last error, and then retrieving it using lasterr.
--> try; error('Test error message'); catch; end; --> lasterr ans = Test error message
Or equivalently, using the second form:
--> lasterr('Test message'); --> lasterr ans = Test message
