How to use profiler to calculate the number of matrix multiplications

I have wrote the followin simple matlab program to simulate a more compex matrix multiplication I am doing.

A = randi(10,10);
B = randi(10,10);
profile on-history
c = A*B;
profile('info')

but from this all I'm getting:

FunctionTable: [0x1 struct] FunctionHistory: [2x0 double] ClockPrecision: 1.0000e-03 ClockSpeed: 3.2010e+09 Name: 'MATLAB' Overhead: 0

This doesn't seem to tell me,I'm looking for a way that'll tell me the number of additions and matrix multiplications since what I am doing is far bigger than what I have here and cannot be computed manually.

I think you want the profile viewer instead:

A = randi(10,10);
B = randi(10,10);
profile on -history
c = A*B;
profile viewer

It doesn't seem to tell me much either:

Profiling is designed for functions, so I suggest the following. Create a function such as this:

function [] = answerTest()

    N = 3000;
    A = randi(N,N);
    B = randi(N,N);
    c = A*B;

end

and then profile the function:

profile on; answerTest(); profile viewer

In the profiler, if you expand the answerTest link, you should see something like the attached screenshot.
