Crate p3_matrix 

p3-matrix

A matrix library for finite-field elements, centered on the Matrix trait and the dense row-major implementation RowMajorMatrix used to store execution traces and LDEs.

Key items:

• Matrix — the core trait, with packed-row access for SIMD-friendly iteration
• dense — RowMajorMatrix and borrowed/mutable views
• bitrev, row_index_mapped, stack, strided, horizontally_truncated — lazy index-remapping and composition wrappers
• extension, interpolation, util — extension-field flattening and evaluation helpers

Part of Plonky3, dual-licensed under MIT and Apache 2.0.
