Find total operations matlab

I need to find the total number of operatons performed in my code.

This is the code I have so far, kinda stuck on figuring out how many operations are present,

A=[2 3 1 -1;5 -2 5 -4;1 -2 3 -3;3 -8 -1 1];
B=[1;5;3;-1];

x=Gauss_Naive(A,B);

x1=x(1,1)
x2=x(2,1)
x3=x(3,1)
x4=x(4,1)

The above is the only way useful meaning can be assigned to "number of operations" for that code.
