Numerical methods for inverting non positive definite matrices Active 7 years ago. Viewed times 2. 1 $\begingroup$ I'm working on a PDE solver and need to invert the following matrix written in block form $\left(\begin{array}{cc} kM & -S \\ -S & M \end{array}\right)$ where M and S are the usual mass and stiffness matrices, so they are. An Inversion-Free Method for Finding Positive Definite Solution of a Rational Matrix Equation special-purpose numerical methods and software for solving large systems of linear and nonlinear. In linear algebra, the Cholesky decomposition or Cholesky factorization (pronounced / ʃ ə. ˈ l ɛ s. k i /) is a decomposition of a Hermitian, positive-definite matrix into the product of a lower triangular matrix and its conjugate transpose, which is useful for efficient numerical solutions, e.g., Monte Carlo was discovered by André-Louis Cholesky for real matrices. If you want more in depth discussion on numerical method s for inverting a matrix, there numerical efficiency and palatalization see these four: positive definite systems. ILUPACK exploits.
