Solving linear equations at each iteration in a for loop.

could you give an example of a code where I solve a system of linear equations (4x4) at each iteration during a for loop. For example: if there are 1000 iterations, at each step the system must be solved.

what is (are) your problems?

let me know where you got stuck please.

• programming?
• solution (mathematical expression)

in MATLAB, linear problem is solved by just using "\".

[LUIS FERNANDO PAZLOPEZ]

I am solving a system of coupled differential equations with the runge kutta method. When creating the for loop, at each iteration, I need to solve a system of linear equations (4x4) and take the results to be used in another equation of the loop.

It sounds that you have difficulties in programming with MATLAB, am I right?

The algorithm is relatively straightfoward and if you are just familiar with MATLAB, I'm sure you can do it in a blink of an eye.

I would reccomend that you should start from scratch -

there are some free trainings available for you:
