ar.linalg.condest
Estimate the condition number of a matrix.
Syntax
ar.linalg.condest(matvec, matvecT, n, options?)
Description
Estimate the condition number of a matrix. Computes both the largest and smallest singular values to estimate the 2-norm condition number κ(A) = σ_max / σ_min.
Parameters
| Name | Description |
|---|---|
| matvec | - Function computing y = A*x (m×n matrix times n-vector) |
| matvecT | - Function computing y = A^T*x (n×m matrix times m-vector) |
| n | - Number of columns (for square matrices, n = m) |
| options(optional) | - Solver options |
Returns
Promise<CondestResult_2>
