Replacing Matlab title name with process Id does not work with startup.m -


i want start matlab , replace title of matlab window process id. created following startup.m file:

cd e:\matlab_files\ jdesktop = com.mathworks.mde.desk.mldesktop.getinstance; jdesktop.getmainframe.settitle(['pid:' num2str(feature('getpid'))]);

now, matlab changes folder e:\matlab_files process id not replaced. once matlab has started , execute 2nd , 3rd line of startup.m, title of matlab window replaced process id.

please explain cause of behaviour.

i using matlab 2009b.

all of graphics haven't finished initialising -> not able replace title (i assume hasn't yet been created).

you can check trying disp jdesktop.getmainframe.gettitle startup.m , see that empty.

thats explanation why - haven't asked fix - assume want one!! ;)

you can fix using timer - note put 60 seconds in timer below - lot less.

function startup   if ~isdeployed  % agood practice use incase ever compile codes.     cd e:\matlab_files\     timerfcn = @updatetitle;     tfcn = timer('startdelay', 60, 'timerfcn', timerfcn );     start(tfcn)   end end function updatetitle(varargin)   jdesktop = com.mathworks.mde.desk.mldesktop.getinstance;   jdesktop.getmainframe.settitle(['pid:' num2str(feature('getpid'))]); end

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
