Module utils 

Utility functions for matrix printing, shape retrieval, identity generation, Kronecker product, trace, transpose operations, …

This module contains small user-facing utilities, plus hidden unstable helpers used by backend implementation crates. It is not meant to be a complete collection of linear algebra utilities at this time.

Functions

diag

Creates a diagonal matrix from a 1D slice, placing its elements on the main diagonal.

identity

Creates an identity matrix of size n x n.

identity_k

Creates a diagonal matrix of size n x n with ones on a specified diagonal.

kron

Computes the Kronecker product of two 2D tensors.

pretty_print

Displays a numeric mdarray in a human-readable format (NumPy-style)

trace

Computes the trace of a square matrix (sum of diagonal elements).

unravel_index

Converts a flat index to multidimensional coordinates.
