The Matrix class represents a mathematical matrix. It provides methods for creating matrices, operating on them arithmetically and algebraically, and determining their mathematical properties (trace, rank, inverse, determinant).

Method Catalogue

To create a matrix:

  • Matrix[*rows]

  • Matrix.[](*rows)

  • Matrix.rows(rows, copy = true)

  • Matrix.columns(columns)

  • Matrix.build(row_count, column_count, &block)

  • Matrix.diagonal(*values)

  • Matrix.scalar(n, value)

  • Matrix.identity(n)

  • Matrix.unit(n)

  • Matrix.I(n)

  • Matrix.zero(n)

  • Matrix.row_vector(row)

  • Matrix.column_vector(column)
