debugging - Matlab custom dbstop handler -

i know people have discussed how make custom dbstop conditions, (such in customize dbstop in matlab)

however, using normal dbstop if error , want know (from process) whether matlab process in debugging state (k>>) or running.

i if had custom dbstop handler function. still want able hands-on debugging normal dbstop if error.

if there other possibilities detect state of matlab outside (>> vs k>>), happy!

let me know idea ;)

timers in matlab can spawn seperate thread wait in can around problem of needing outside current matlab instance. can set timer check if debug mode active , if something.

a example function check if debug mode active , if something:

function mycallbackfunction(~,~)         if feature('isdebugmode') % undocumented catzlovejazz          load handel         sound(y,fs) 

the 2 previous lines attention grabbing example, other possibilities use beep, write file, or run commands or function.

        evalin('base','stop(timerhandle)') % stop timer     end end 

this function modified evaluate 'attention grab' once , reset once debug mode no longer active. relies on stopping , manually restarting timer.

(note: previous version had else redundant not run while workspace busy)

now create timer object.

timertic=4; % how timer checks  timerhandle = timer(); timerhandle.startdelay = timertic; timerhandle.period = timertic; timerhandle.executionmode = 'fixedrate'; timerhandle.taskstoexecute = inf; timerhandle.timerfcn = @mycallbackfunction; 

and start timer call

start(timerhandle) 

the timer automatically stop after running attention grabbing lines. if debug mode never entered timer keep running , need stoped manually stop(timerhandle)

remember run delete(timerhandle) once finished remove object before clearing timerhandle variable
