spinguin.core.sparse_dot#

This module provides a Cython wrapper for the sparse matrix multiplication algorithm written in C++.

sparse_dot(A: csc_array, B: csc_array, zero_value: float) → csc_array#

Custom matrix multiplication for SciPy CSC matrices.

Parameters:

  • A (csc_array) – Matrix A.

  • B (csc_array) – Matrix B.

  • zero_value (float) – Threshold below which a number is considered zero in the result matrix.

Returns:

C – Result of the matrix multiplication C = A @ B.

Return type:

csc_array
