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

NameDescription
matvec- Matrix operator A (m x n)
m- Number of rows in A
n- Number of columns in A

Returns
