The CoinUtils project is a collection of open-source utilities developed and used by a variety of other projects in the COIN-OR repository. The project includes classes for storing and manipulating sparse matrices and vectors, performing matrix factorization, parsing input files in standard formats, building representations of mathematical programs, comparing floating point numbers with a tolerance, performing simple presolve operations, and warm starting algorithms for mathematical programs, among others.

给定n个矩阵{A1,A2,…,An}，其中Ai与Ai+1是可乘的，i=1,2,…,n-1。考察这n个矩阵的连乘积A1A2…An。由于矩阵乘法满足结合律，故计算矩阵的连乘积可以有许多不同的计算次序，这种计算次序可以用加括号的方式来确定。若一个矩阵连乘积的计算次序完全确定，则可以依此次序反复调用2个矩阵相乘的标准算法（有改进的方法，这里不考虑）计算出矩阵连乘积。若A是一个p×q矩阵，B是一个q×r矩阵，则计算其乘积C=AB的标准算法中，需要进行pqr次数乘。

hyperbolic Householder transformation的功能类似于Householder transformation，其作用是将被变换向量映射成双曲模与之相同的其它向量。其应用之一是快速QR分解。

The "GEE! It s Simple" package illustrates Gaussian elimination with partial pivoting, which produces a factorization of P*A into the product L*U where P is a permutation matrix, and L and U are lower and upper triangular, respectively. The functions in this package are accurate, but they are far slower than their MATLAB equivalents (x=A\b, [L,U,p]=lu(A), and so on). They are presented here merely to illustrate and educate. "Real" production code should use backslash and lu, not this package.
