MATLAB: set title of non-java command window -


question

how set command window title matlab window launched without desktop , without java?

  • matlab ver of primary interest: 2012a & later
  • os needed: windows (xp) primarily; more general preferred
  • ideal solution: sets title in resulting window produced "mat" function described below.
  • alternate solution: set command window title in window produced "matj" function described below.

background

i have anonymous functions launch "barebones matlab" windows (each executing main matlab window's terminal.

mat  = @(scmd) system(['matlab.exe -nodesktop -nosplash -nojvm -r "' scmd ';" &']); matj = @(scmd) system(['matlab.exe -nodesktop -nosplash -r "' scmd ';" &']);

the "matj" window more ram-memory intensive produced "mat".

i aware of techniques set title in java-enabled windows, such following (which, curiously, did not work in "matj" window):

cmdtitle = @(st) com.mathworks.mde.desk.mldesktop.getinstance.getclient('command window').gettoplevelancestor.settitle(st)

why need this/what i'm doing this

i divvy memory-intensive non-plotting matlab tasks these barebones-windows "master" matlab window (fully loaded java & other bells/whistles). setting title these allow me give them visual tag regarding window's assigned task.

also, helpful able expand displayed-text buffer in these barebones windows (it seems they're limited ~500 lines on computer). work-around title-setting issue display string terminal once barebones window displays, limited buffer prevents first line persisting.

suggestions on better/alternate ways achieve these objectives appreciated, time in reading/answering. thank & day.

by sounds of doing akin batch processing. may want matlab parallel computing toolbox. more recent versions of & matlab allow treat computer mini compute-cluster , fire off batch jobs solve problem neatly.

alternatively, if haven't got license go windows api route setting window title, , wrap in mexfunction. since interesting have hacked code this:

//include windows api functions #include <windows.h> //include matlab mex function stuff #include "mex.h"  dword processid; //the process id of current matlab  //callback function, bit sets window text bool callback settitleenum( hwnd hwnd, lparam lparam ) {         dword dwid ;     //get process of window called on     getwindowthreadprocessid(hwnd, &dwid);      //if our matlab instance, set title text     if(dwid == processid) setwindowtext(hwnd, (const char*) lparam);     return true; }  void mexfunction(int nlhs, mxarray *plhs[], int nrhs, const mxarray *prhs[])  {     //get process id of instance of matlab     processid = getcurrentprocessid();       if (nrhs > 0) { //if have been given title         char * title = mxarraytostring(prhs[0]); //get char* string              //get open windows , call settitleenum function on them         enumwindows((wndenumproc)settitleenum, (lparam) title);                 mxfree(title);//free title string.     } }

i compiled above code in matlab using visual studio 2010 express , worked fine me, both in restricted command line version , normal full desktop matlab.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
