Particular libraries discussed are meschach , which provides routines for operating on matrices and vectors for projects coded in c , the cooperware matrix cwmtx for c coding , and blitz , which provides an n - dimensional array class for c with integral , floating , complex , and well - behaved , user - defined types 在这里具体讨论的库有三个: meschach库为c代码编写的项目提供例程,用于矩阵和向量的运算; cooperware matrix ( cwmtx )库可用于c + +代码编写; blitz库为c + +提供可用整数、浮点数、复数和规范的用户定义的类型的n维数组类。
