Expand description

Parallel sparse matrix-vector multiplication for CSR format

Performs y = A * x where A is a sparse matrix in CSR format, using parallel processing and SIMD acceleration when beneficial.

§Arguments

  • y - Output vector (will be overwritten)
  • rows - Number of rows in the matrix
  • indptr - Row pointer array (length = rows + 1)
  • indices - Column indices array
  • data - Non-zero values array
  • x - Input vector
  • options - Optional configuration (uses default if None)

§Panics

Panics if array dimensions are inconsistent
