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.
