dask.array.linalg.sfqr

dask.array.linalg.sfqr(data, name=None)[source]

Direct Short-and-Fat QR

Currently, this is a quick hack for non-tall-and-skinny matrices which are one chunk tall and (unless they are one chunk wide) have chunks that are wider than they are tall

Q [R_1 R_2 …] = [A_1 A_2 …]

it computes the factorization Q R_1 = A_1, then computes the other R_k’s in parallel.

Parameters
data: Array
