Setting the name of the Matlab Command Window

6 visualizzazioni (ultimi 30 giorni)
Hello
for an automatisation process I start Matlab(Simulink) from the commandline, and for this purpose with the setting "-nodesktop"
I will get a Command window, which looks something like this

Is it possible to add something to the window title, to make it easier to find the proper window if several are started in parallel
Something like the filename, currenworking dir or even a "generic" text would be nice.
Via commandline, or via m-code

No, there is no way to modify the title of the MATLAB command window.

Not what I hoped for, but at least I have the information now.
Thanks

I am looking for the solution of the same question. I tested and the following solution works:
  1. Copy and paste the code to e.g. 'setWindowTitle.cpp';
  2. Compile the cpp to a MEX function by calling mex setWindowTitle.cpp in MATLAB. (Run mex -setup to setup the compiler).
  3. Call the function directly as the file name: e.g. setWindowTitle('New Window Title') or you can wrap it as a method of a class or a package function.
//Include the windows api functions
#include <Windows.h>
//include the matlab mex function stuff
#include "mex.h"
DWORD processID; //the process id of the current matlab
//Callback function, this is the bit that sets the window text
BOOL CALLBACK SetTitleEnum( HWND hwnd, LPARAM lParam ) {
DWORD dwID ;
//get the process of the window this was called on
GetWindowThreadProcessId(hwnd, &dwID);
//if it is our matlab instance, set the title text
if(dwID == processID) SetWindowText(hwnd, (const char*) lParam);
return true;
}
void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[])
{
//get the process id of this instance of matlab
processID = GetCurrentProcessId();
if (nrhs > 0) { //if we have been given a title
char * title = mxArrayToString(prhs[0]); //get it as a char* string
//get all open windows and call the SetTitleEnum function on them
EnumWindows((WNDENUMPROC)SetTitleEnum, (LPARAM) title);
mxFree(title);//free the title string.
}
}
