Numpy version 1.19.3 (previous to 1.19.

myMatrixTools.py - constains few basic matrix manipulation and analysis functions for usage.

main2.py - constains larger user-input of size N, matrix a and vector b.

main.py - contains basic usage demonstration of jacobi_calc() or gauss_seidel_calc(), using a 3x3 matrix, and basic arguments.

rel_diff, the relative difference between last 2.

If max_iter is None, the default value will set as 200.

max_iter, the maxim number of possible iterations to receive the most exact solution.

If tolerance is None, the default value will set as 1e-16.

tolerance, the desired limitation of tolerance of solution's anomaly.

For example, once we have computed 1 (+1) from the first equation, its value is then used in the second equation to obtain the new 2 (+1), and so on. If x is None, the initial guess will bw determined as a vector of 0's. With the Gauss-Seidel method, we use the new values (+1) as soon as they are known. if b is None - the functions returns None. If a is None or NxM, where N != M - the functions returns None.

a, the NxN matrix that the method is being performed on.

The algorithms will terminate when the change in x is less than tolerance, or if max_iter iterations have been exceeded.įor each function: (jacobi_calc() or gauss_seidel_calc())

Both are based on fixed point iteration method.
