由正定矩阵的定义即知ATA是正定矩阵。正定矩阵是一种实对称矩阵。正定二次型f(x1，x2，…，xn)=X′AX的矩阵A(或A的转置)称为正定矩阵。在线性代数里，正定矩阵 (positive definite matrix) 有时会简称为正定阵。在双线性代数中，正定矩阵的性质类似复数中的正实数。与正定矩阵相对应的线性算子是...
The problem of computing the triangular factors of a square, real, symmetric, and positive definite matrix by using the facilities of a multiprocessor MIMD-type computer is considered. The parallel algorithms based on Cholesky decomposition and Gaussian elimination are derived and analyzed in terms of...
