Number of Calls - Matlab Profiler Data

Dear Colleagues,

We are testing several Matlab software functional prototypes for algorithm correctness, then performance optimization will be done. Initially, optimization is focussed on the number of calls (references) to computationally expensive routines and primitives to identify potential issues in For Loops construction. Here is a summary of of the number of calls data in a Matlab Profiler execution:

MATLAB Profiler Output:

Function Name Calls Total Time Self Time

Run Main 1 M sec m sec

Subroutine 1 K N sec n sec

Subroutine 2 2K*L J sec j sec

Code Example:

Subroutine 1

For j = 1, L

Call Subroutine 2

Inline code1

:Ÿ

Ÿ Call Subroutine 2

:

Inline code2

End For

Variables ranges for this example:

0 < m ≤ M

0 < n < N

0 < j < J

L ≥ 1

We assume that number of calls for the nesting described will follow this pattern.

Can you point your question on this?

[Evans Harrigan]

Is my formula for the # of calls to Subroutine 2 in notional code above correct?

[Mallika]

what is total number of calls in the profile Report

[Fangjun Jiang]

@Mallika, The Profiler is run on "Main". It runs only once. If "Subroutine 1" is called "K" times, then "Subroutine 2" is called 2K*L times based on the illustration. All numbers are correct.
