我们讨论了用于测试线性代数软件的一组测试矩阵生成器的设计和实现。这些例程生成具有某些属性的随机矩阵,这些矩阵可用于测试线性方程求解,最小二乘和特征性组件软件。这些属性包括频谱,对称性,带宽,标准,稀疏性,调理性(相对于反转或本本本特征),类型(真实或复杂)和存储方案(密集,包装或带子)
We discuss the design and implementation of a suite of test matrix generators for testing linear algebra software. These routines generate random matrices with certain properties which are useful for testing linear equation solving, least squares, and eigendecomposition software. These properties include the spectrum, symmetry, bandwidth, norm, sparsity, conditioning (with respect to inversion or for the eigenproblem), type (real or complex), and storage scheme (dense, packed, or banded)
