Dear all,
I created an app which includes 1 file .mlapp (~2.5k lines) and 11 other function files .m.
This App read csv files, analyzes and virualize data to plots and uidata table.
Because there are many callback functions (18 functions), so it seem slow, and sometimes gets stuck, freeze.
I would like to improve by separates functions to other file (function or class file).
But I am wondering about 2 problems:
  • How to instead properties of app designer to other class file? and callbacks
  • It's really improves speed?
Do anyone have ideas??

I don't see adding meta-programming that need to check for a freeze doing any good. You can add a time-out, but on slow computers that will break execution.
My inital concern about only 18 function for several thousand lines of code still remains. For me that is a code smell.
You could try extracting the bulk of the code to external files. That seems an easy thing to try.

"I heard that if app designer greater than 1500 lines, it will run slow. I am not sure that if it is true or not."
False.
