是否有一个很好的用于向量和矩阵的PHP库? [英] Is there a good PHP library for vectors and matrices?

问题描述

我需要一个用于向量和矩阵的PHP库.我要寻找的程式库应包含矩阵乘法，向量余弦相似度，卷积等功能.

I need a PHP library for vectors and matrices. The library I'm looking for should include functions like matrix multiplication, vector cosine similarity, convolution etc.

我还希望这样的库能够对稀疏向量和矩阵进行适当的紧凑内部表示.

I also expect such a library to have a proper compact internal representation of sparse vectors and matrices.

我正在使用PHP 5.2.
