WebOct 16, 2008 · The Direct solver uses direct matrix factoring methods (such as Gaussian elimination) to invert the Jacobian matrix. This solver is recommended for small circuits with relatively few devices, non-linear components, and number of harmonics. For large circuits, the direct solver will be slow and inefficient. WebJun 28, 2016 · 2 Answers Sorted by: 2 The "big matrix" problem is certainly one reason. Another is that iterative solvers can be run until the result is "good enough", so you are checking the results every k-th iteration. Another reason is that the explicit matrix may not be available, so you can get Ax for any specified x, but not A itself. Share Cite Follow
