get last recorded error message
[str,n,line,func] = lasterror() [str,n,line,func] = lasterror(opt)
a vector of character strings or an empty matrix. The last recorded error message.
an integer, 0 or the last recorded error number.
an integer, 0 or the last recorded function line number.
a string, the last recorded function name.
a boolean, if %t recorded message is cleared. Default is %t.
Each time an error occurs, the Scilab error handler records it in an
internal table (only the last one is retained). The
lasterror function allows to get the message, the error
number, the current function (if any) and the current line number in the
current function out of this table.
The reported line number is the physical line number where the last error occurred. Note that Scilab versions before 5.0 used to report the logical line number of the last error. There is a difference only if the function in error includes continued lines (see dot) before the point where the error happened.
This function is especially useful while using execstr.
The recorded error message may be retained for a further call to
- execstr — execute Scilab code in strings
- error — reports a run time error
- errclear — clears the last error (if its number matches a given one)
- edit_error — opens in scilab editor the source of the last recorded error
