A PHP library providing a Matrix class with common linear algebra operations such as addition, multiplication, inverse, determinant, transpose, and LU/QR decomposition. It is installable via Composer and designed for use in PHP applications needing matrix math.

Use cases

• perform matrix multiplication in php
• calculate the determinant of a matrix in php
• invert a matrix in php
• solve linear equations A.X = B in php
• compute LU or QR decomposition in php
• transpose or find the trace of a matrix in php

When to choose

• you need basic matrix operations in a PHP project
• you want a lightweight Composer-installable linear algebra library
• you need LU or QR decomposition in PHP

When to avoid

• you need eigenvalue decomposition or Cholesky decomposition (not yet implemented)
• you need high-performance numerical computing (use a native extension or another language)
• you need tensors or N-dimensional arrays rather than 2D matrices
