Miscellaneous Linear Algebra Routines (numojo.routines.linalg.misc)

This module provides miscellaneous linear algebra routines, such as extracting diagonals and checking for symmetry.

Functions

diagonal

diagonal[dtype: DType](a: NDArray[dtype], offset: Int = 0) -> NDArray[dtype]

Returns specific diagonals. Currently supports only 2D arrays.

Parameters:

• dtype (DType): Data type of the array.

Args:

• a (NDArray): An NDArray.
• offset (Int): Offset of the diagonal from the main diagonal.

Returns:

• NDArray

Raises

Error: If the array is not 2D.

Error: If the offset is beyond the shape of the array.

issymmetric

issymmetric[dtype: DType](A: Matrix[dtype], rtol: Scalar[dtype] = 1.0000000000000001E-5, atol: Scalar[dtype] = 1.0E-8) -> Bool

Returns True if A is symmetric, False otherwise.

Parameters:

• dtype (DType): Data type of the Matrix Elements.

Args:

• A (Matrix): A Matrix.
• rtol (Scalar): Relative tolerance for comparison.
• atol (Scalar): Absolute tolerance for comparison.

Returns:

• Bool
