How do I execute "clear all" without affecting the breakpoints in MATLAB 8.1 (R2013a)?

When coding interactively, all the breakpoints are cleared when I execute "clear all".

For example, executing the following in MATLAB clears the breakpoints.

clear all

Is there a way to clear everything except the breakpoints?

MATLAB 8.1 (R2013a) currently does not have the ability to retain breakpoints while clearing all the variables in the workspace after issuing "clear all."

As a workaround, the following example function, clearNoBP, clears all the workspace data without removing the break points.

The functions DBSTATUS and DBSTOP are used to get this functionality.

 

function clearNoBP(varargin)
    % returns all breakpoints into 's'
    s = dbstatus;
    
    % records all input arguements (varargin) into 'options'
    options = '';
    for i = 1:numel(varargin)
        options = [options,',''',varargin{i},''''];
    end
    
    % Execute built-in clear function with input options in specified caller workspace
    evalin('caller',['builtin(''clear''',options,')']);
    
    % resets the breakpoints
    dbstop(s);
end

The above function records all the current breakpoints, evaluates the built-in CLEAR function only in the caller’s workspace and re-sets all the breakpoints.

In order to use clear allowing the breakpoints to remain, execute the following command in the command window,

clearNoBP all

Also, refer to the following documentation link to see all the available input options with the CLEAR function.
