MATHEMATICA SYMBOLIC SOLVER HOW TO

"LinearSolve." Wolfram Language & System Documentation Center. Wolfram Research (1988), LinearSolve, Wolfram Language function, (updated 2022). Upper bound on the number of additional nonzero elements in a row introduced by the ILUT preconditionerĭrop tolerance (any element of magnitude smaller than this tolerance is treated as zero )Ĭite this as: Wolfram Research (1988), LinearSolve, Wolfram Language function, (updated 2022). Possible suboptions for "Preconditioner" include: LinearSolve m and LinearSolveFunction provide an efficient way to solve the same approximate numerical linear system many times. The matrix m can be square or rectangular. The argument b can be either a vector or a matrix. Possible settings for "Preconditioner" include:Ī preconditioner based on an incomplete LU factorization of the original matrix without fill-inĪ variant of ILUT with column permutation LinearSolve works on both numerical and symbolic matrices, as well as SparseArray objects. Iterative method for Hermitian positive definite matrices Iterative method for arbitrary square matrices The tolerance used to terminate iterations

MATHEMATICA SYMBOLIC SOLVER HOW TO

How to apply a preconditioner ( "Left" or "Right" )Ī norm function that computes a norm of the residual of the solution The size of the Krylov basis (GMRES only ) The following suboptions can be specified for the method "Krylov":

Explicit Method settings for approximate numeric matrices include:Ĭholesky method for positive definite Hermitian matrices.

Explicit Method settings for exact and symbolic matrices include:īareiss method of division-free row reduction.

With Method-> Automatic, the method is automatically selected depending upon input.

The ZeroTest option only applies to exact and symbolic matrices.Test to determine when expressions are zero LinearSolve has the following options and settings:.In addition to finding solutions to equations, WolframAlpha also plots the equations and their solutions. Solving equations yields a solution for the independent variables, either symbolic or numeric. For underdetermined systems, LinearSolve will return one of the possible solutions Solve will return a general solution. Algebraic equations consist of two mathematical quantities, such as polynomials, being equated to each other.LinearSolve is equivalent to LinearSolve.LinearSolve and LinearSolveFunction provide an efficient way to solve the same approximate numerical linear system many times.The matrix m can be square or rectangular.The argument b can be either a vector or a matrix.LinearSolve works on both numerical and symbolic matrices, as well as SparseArray objects.
