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:.

For underdetermined systems, LinearSolve will return one of the possible solutions Solve will return a general solution.

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.
