Memory-efficient sparse matrix-vector multiplication using streaming

This implementation processes the matrix in chunks to minimize memory usage while maintaining computational efficiency.

§Arguments

  • matrix - The sparse matrix
  • x - The input vector
  • chunk_size - Number of rows to process at once
  • memory_tracker - Optional memory usage tracker

§Returns

The result vector y = A * x
