# Half-precision floating-point matrices

Perform operations on matrices that contain half-precision floating-point elements.

## Overview

Overview A matrix is a 2D array of values arranged in rows and columns. The simd library provides support for matrices of up to four rows and four columns. It uses a column-major naming convention; for example, a simd_half4x2 is a matrix that contains four columns and two rows.
