#5381: [with patch, needs review] Refactor matrix kernels
----------------------------+-----------------------------------------------
Reporter: rbeezer | Owner: rbeezer
Type: task | Status: new
Priority: minor | Milestone: sage-4.0
Component: linear algebra | Keywords: matrix kernel refactor
----------------------------+-----------------------------------------------
Comment(by rbeezer):
New patch ("_3") addresses all reviewer comments above, though I could
only find one function that needed to have doctests added
({{{_kernel_matrix_using_pari}}}).
Passed the following tests:[[BR]]
sage -testall[[BR]]
sage -t --randorder sage/matrix/*[[BR]]
sage -docbuild reference pdf[[BR]]
Apply just this new (third) patch, which was built on 3.4.2.alpha0
Minh - timings are getting a bit dated, but are probably still accurate,
though most of the speedup came from improvments discovered in transposes
while working through this. You could say "a 16% improvement in right
kernels by eliminating paired transposes."
