ar.operators.transposeMatvec
Create a transpose operator via explicit computation.
Syntax
ar.operators.transposeMatvec(matvec, m, n)
Description
Create a transpose operator via explicit computation. This builds A^T by probing A with standard basis vectors. WARNING: This is O(n²) and should only be used for small matrices or when no other option exists. For large matrices, prefer providing an explicit transpose operator.
Parameters
| Name | Description |
|---|---|
| matvec | - Matrix operator A (m x n) |
| m | - Number of rows in A |
| n | - Number of columns in A |
Returns
