Python Matrix

A simple matrix library for Python 3

Usage

Initialize a matrix object by passing the number of rows and columns. Rows and columns must be at least 2.

from matrix import Matrix

mat = Matrix(3, 3)

mat.fillRow(0, ['a', 'b', 'c'])
mat.fillRow(1, ['d', 'e', 'f'])
mat.fillRow(2, ['g', 'h', 'i'])

print(mat.getRows())
# [['a', 'b', 'c'], ['d', 'e', 'f'], ['g', 'h', 'i']]

Methods

• get (row:int, col:int, default=None)
  • Get cell value by row and column
• set (row:int, col:int, value)
  • Set cell value by row and column
• fillRow (row:int, values:list)
  • Fill row with specified values
• fillColumns (col:int, values:list)
  • Fill row with specified values
• getRow (row:int)
  • Get row by index
• getColumn (col:int)
  • Get column by index
• getDiagonal (row:int, col:int, forward=False)
  • Get diagonal values that intersects with row and col
  • Retrieve forward diagonal values by passing True as the third parameter
• getRows
  • Get all rows
• getColumns
  • Get all columns
• getDiagonals (forward=True)
  • Get all diagonal values, direction is determined by the forward parameter

Properties

• numRows - Total number of rows
• numColumns - Total number of columns
