# dbclear

## Purpose

Clear breakpoints.

## Synopsis

    dbclear at lineno in mfilename
    dbclear all in mfilename
    dbclear all
    dbclear in mfilename
    dbclear if error
    dbclear if naninf
    dbclear if infnan

## Description

The `dbclear` command removes the breakpoint(s) set by a corresponding `dbstop` command.

`dbclear` `at` `lineno` `in` `mfilename` removes the breakpoint set at the specified line in the specified file.

`dbclear` `all` `in` `mfilename` removes all breakpoints in the specified M-file.

`dbclear` `all` removes all breakpoints in all M-file functions.

`dbclear` `in` `mfilename` removes the breakpoint set at the first executable line in the specified file.

`dbclear` `if` `error` clears the `dbstop` `error` statement, if set. If a runtime error occurs after this command, MATLAB terminates the current operation and returns to the base workspace.

`dbclear` `if` `naninf` and `dbclear` `if` `infnan` clear the `dbstop naninf` or `dbstop` `infnan` statements respectively, if set.

The at, in, and if keywords, familiar to users of the UNIX debugger dbx, are optional.
