How can I merge two profiler results?

2 views (last 30 days)
I want to find out why two similar processes have very different runtimes.
To do this, I need to be able to merge the two Profiler tables (Function Name, Calls, Total Time, Self Time) by Function Name, and compute the time difference for each function name.
Can MATLAB do this?
Thank you.

Alternatively, can MATLAB save the Profiler output table (Function Name, Calls, Total Time, Self Time) to a text or spreadsheet file?
Thank you.

profile on; categorical(1:10); profile off;
p = profile("info");
struct2table(p.FunctionTable)
ans = 20×12 table
