how to change compiled app icon (using app designer) on the app and windows taskbar

86 views (last 30 days)
Could someone please help me to modify the default icon of MATLAB to custom icons on the compiled app using App Designer on both the app and the windows taskbar?
Please see the red square on the following figure which highlights the icons that I want to replace with custom icons.
thanks a lot!

Could not find a way to do it either, still stuck with MatLab icon in the title bar and the win taskbar (Win10 as well).
Flying MatLab's colours is all very well but this still sucks : I'd love to be able to use different icons for different pop-ups or windows in my app...

I'm negative on this and would not waste time digging into this.
My only hope is they would add this feature in one of their next releases.

Starting in R2020b we can use the UIFigue.Icon property, for example:
UIFigure.Icon = 'myicon.png'

I have MatLab ver 2021b. You can change the default ICON like shown in this picture.

See code attached - put the image in the same folder of the app1.mlapp.
I still don't know how to treat the taskbar icon (Matlab icon). The taskmanager icon is from MatlabWindow.exe (the Matlab Runtime executable file that is called by your standalone app).
