re-matrix 0.0.8

Simple python package

re-matrix

This library row includes functions for row reducing matrices along with some basic matrix math functions. For example, the following code reduces an example matrix.

from re_matrix import row_reducer

example_matrix = [[8, 2, 3, 4],
                  [5, 3, 7, 8],
                  [7, 9, 2, 5]]
reduced_matrix = row_reducer.get_row_reduced_matrix(example_matrix)
row_reducer.pretty_print_matrix(reduced_matrix)

Here is the output in the console:

------------------
 1.0   0.0  0.0  0.0620915032679738
 0.0   1.0  0.0  0.2908496732026147
-0.0  -0.0  1.0  0.9738562091503268
------------------

You can also get the solutions directly using this code:

import re_matrix

example_matrix = [[8, 2, 3, 4],
                  [5, 3, 7, 8],
                  [7, 9, 2, 5]]
reduced_matrix = re_matrix.get_row_reduced_matrix(example_matrix)
solution_set = re_matrix.get_matrix_solutions(reduced_matrix)
re_matrix.print_solution_set(solution_set)

which produces this output:

the solution set is: 
x_0 = 0.0620915032679738
x_1 = 0.2908496732026147
x_2 = 0.9738562091503268

You can also use the analyze_and_row_reduce_matrix function

import re_matrix

example_matrix = [[8, 2, 3, 4],
                  [5, 3, 7, 8],
                  [7, 9, 2, 5]]
reduced_matrix = re_matrix.analyze_and_row_reduce_matrix(example_matrix)

original matrix:
------------------
8  2  3  4
5  3  7  8
7  9  2  5
------------------
row reduced matrix:
------------------
 1.0   0.0  0.0  0.0620915032679738
 0.0   1.0  0.0  0.2908496732026147
-0.0  -0.0  1.0  0.9738562091503268
------------------
the solution set is: 
x_0 = 0.0620915032679738
x_1 = 0.2908496732026147
x_2 = 0.9738562091503268
The solution set solves the original matrix
