SPDMatrixInverse_CholeskyDecomposition_ForwardBackwardSubstitutionMatlab脚本和函数用于将指定的对称正定(SPD)矩阵分解为下三角矩阵,从中可以找到逆矩阵并测试对称正定性。这些函数利用Cholesky分解算法,将SPD矩阵分解为下三角矩阵,然后通过前向和后向替换进行求逆操作。该过程保证了逆矩阵的准确性和稳定性,并且可以用于验证...
乔里斯基分解(Choleskydecomposition)乔⾥斯基分解(Choleskydecomposition)在线性代数中,乔⾥斯基分解是将⼀个正定Hermite矩阵分解成为⼀个下三⾓阵和它的共轭转置阵的乘积。如果矩阵A是正定Hermite阵,那么矩阵A可以做如下分解: 其中L是⼀个下三⾓矩阵且主对⾓线元素严格正定,L*是L的共轭转置矩阵。这就 是...
