warp.optim.linear.aslinearoperator

warp.optim.linear.aslinearoperator(A)

Cast the dense or sparse matrix A as a LinearOperator.

A must be of one of the following types:

• warp.sparse.BsrMatrix

• two-dimensional warp.array; then A is assumed to be a dense matrix

• one-dimensional warp.array; then A is assumed to be a diagonal matrix

• warp.optim.linear.LinearOperator; no casting necessary

Parameters:

A (array | BsrMatrix | LinearOperator)

Return type:

LinearOperator
