gko::matrix

Matrix formats and matrix-like operators. Every type below is a LinOp — composable through apply, transformable through clone and copy, and shareable across executors. For background on the format trade-offs see the Matrix formats concept page.

Sparse formats

• Csr — compressed sparse row.

• Coo — coordinate format.

• Ell — equal-length rows.

• Sellp — sliced ELL with permutation.

• Hybrid — ELL + COO fall-back.

• Fbcsr — fixed-size block CSR.

• SparsityCsr — sparsity pattern only.

Dense

• Dense — column-major dense matrix.

Utility operators

• Identity — identity LinOp.

• Diagonal — diagonal matrix.

• Permutation — row/column permutation.

• ScaledPermutation — permutation with row scaling.

• RowGatherer — gather rows by index.
