In Section 3, we present the main result of this paper, that is, the improved sparse matrix multiplication algorithm. In Section 4, we use similar ideas to obtain an improved algorithm for the multiplication of …

A common operation on sparse matrices is to multiply them by a dense vector. In such an operation, the result is the dot-product of each sparse row of the matrix with the dense vector.

Aug 2, 2022 · Given two sparse matrices (Sparse Matrix and its representations | Set 1 (Using Arrays and Linked Lists)), perform operations such as add, multiply or transpose of the matrices in their …

In some cases, the result might be sparse even though the matrix has few zero elements. Matrix concatenation using either the cat function or square brackets produces sparse results for mixed …

In sparse matrix multiplication, two sparse matrices that are multiplied can be accessed either by row or column. This derives four SpGEMM formulations, which are row-by-row (RbR), row-by-column/inner …
