pycauset.TriangularFloatMatrix

A memory-mapped upper triangular matrix storing 64-bit floating point numbers. Inherits from MatrixBase.

Constructor

pycauset.TriangularFloatMatrix(n: int, has_diagonal: bool = False)

Creates a new triangular matrix of size n x n.

  • n: The number of rows/columns.
  • has_diagonal: If True, the matrix stores and allows access to the diagonal elements. If False (default), the matrix is strictly upper triangular (diagonal is implicitly 0).

Properties

shape

Returns a tuple (rows, cols) representing the dimensions of the matrix.

Methods

Indexing

Element access uses NumPy-style indexing:

x = M[i, j]
M[i, j] = value

multiply(other: TriangularFloatMatrix) -> TriangularFloatMatrix

Multiply this matrix by another TriangularFloatMatrix.

invert() -> TriangularFloatMatrix

Compute the inverse of the matrix.

__repr__() -> str

String representation of the matrix.
