Project description

LIB-B

A library contains implements of factorization supporting multiple methods and data types.

  • LU Factorization
  • Schmidt Decomposition (classical/modified)
  • Householder Reduction
  • Givens Reduction

Environment

Python 3.4 or higher

Install

pip install lib-b

Usage

# libb -h

If you have some matrix file which is split by white space:

# libb -f matrix lu|cs|ms|h|g

Usage in script

Import it:

import libb

Load matrix(from stdin or opened file):

A_matrix, row_num, col_num = libb.LoadMatrix(src=stdin)

Apply methods on matrix (any struct that supports index operator []) and fetch the result:

P, L, U = libb.LUFactorization(A=A_matrix)
Q, R = libb.ClassicalSchmidtDecomposition(A=A_matrix)
Q, R = libb.ModifiedSchmidtDecomposition(A=A_matrix)
Q, R = libb.HouseholderReduction(A=A_matrix)
Q, R = libb.GivensReduction(A=A_matrix)
