create a variable addsub for an operation count for gauss jordan in matlab

To create a variable "addsub" for an operation count in Gauss-Jordan elimination method in Matlab, you can follow these steps:

1. First, declare the variable "addsub" and initialize it to zero:

main.m
addsub = 0;
12 chars
2 lines

2. Increment the variable every time there is an addition or subtraction operation in the Gauss-Jordan method:

main.m
addsub = addsub + 1; % Increment after an operation
52 chars
2 lines

3. At the end of the Gauss-Jordan method, the variable "addsub" will hold the total count of addition and subtraction operations performed during the process.

You can integrate these steps within your Matlab code for implementing the Gauss-Jordan method to keep track of the operation count.
