Can the Code Profiler be used programmatically to profile an app in App Designer?

I am aware that I can open the Profiler, click 'start profiling' run my app, then stop profilling and view it.

Can I initiate the start and stop of the profiling programatically?

tic/toc is good, but that's better to test implementations. the Profiler is great to look at overall where my code is slow.

"Can I initiate the start and stop of the profiling programatically?"

Yes. See the "action" input argument part of the documentation for profile:

https://www.mathworks.com/help/matlab/ref/profile.html#f8-618415-action

Using some of those actions, maybe you can do what you want:

% turn on and start the profiler:
profile('on');
profile('resume');

% run a function:
test_func();

% get the current profiler info:
s = profile('info')

s = struct with fields:
      FunctionTable: [44×1 struct]
    FunctionHistory: [4×396 double]
     ClockPrecision: 1.0000e-06
         ClockSpeed: 3.4554e+09
               Name: 'MATLAB'
           Overhead: 0

s.FunctionTable

ans = 44×1 struct array with fields:
    CompleteName
    FunctionName
    FileName
    Type
    Children
    Parents
    ExecutedLines
    IsRecursive
    TotalRecursiveTime
    PartialData
    NumCalls
    TotalTime

% get the info about the function test_func:
s.FunctionTable(strcmp({s.FunctionTable.FunctionName},'test_func'))

ans = struct with fields:
          CompleteName: '/users/mss.system.IR6him/test_func.m>test_func'
          FunctionName: 'test_func'
              FileName: '/users/mss.system.IR6him/test_func.m'
                  Type: 'M-function'
              Children: [0×1 struct]
               Parents: [1×1 struct]
         ExecutedLines: [5×3 double]
           IsRecursive: 0
    TotalRecursiveTime: 0
           PartialData: 0
              NumCalls: 1
             TotalTime: 6.6100e-04

% stop the profiler:
profile('off');
