errclear
clears the last error (if its number matches a given one)
Syntax
errclear() errclear(n)
Description
clears the action (error-handler) connected to error of type
n.
If n is positive (n > 0), it is the number of
the cleared error ; otherwise if (n <= 0) all errors are cleared
(default case).
Examples
a = 1; try, b = undefinedvariable + a; end [m,n0] = lasterror(); n0 try, b = undefinedvariable + a; end errclear() [m,n] = lasterror(); n try, b = undefinedvariable + a; end errclear(100) [m,n] = lasterror(); n try, b = undefinedvariable + a; end errclear(999) [m,n] = lasterror(); n
--> try, b = undefinedvariable + a; end --> [m,n0] = lasterror(); --> n0 n0 = 999. --> try, b = undefinedvariable + a; end --> errclear() --> [m,n] = lasterror(); --> n n = 0. --> try, b = undefinedvariable + a; end --> errclear(100) --> [m,n] = lasterror(); n n = 999. --> try, b = undefinedvariable + a; end --> errclear(999) --> [m,n] = lasterror(); n n = 0.
