#5364: unused maxima builtin functions for matrices over SR
----------------------------+-----------------------------------------------
Reporter: ylchapuy | Owner: was
Type: defect | Status: closed
Priority: major | Milestone: sage-duplicate/invalid/wontfix
Component: linear algebra | Resolution: invalid
Keywords: |
----------------------------+-----------------------------------------------
Changes (by mhansen):
* status: new => closed
* resolution: => invalid
* milestone: sage-4.0.1 => sage-duplicate/invalid/wontfix
Comment:
This was fixed by converting symbolic matrices to use Sage's generic dense
matrix backend:
{{{
sage: m = MatrixSpace(SR, 1000, 1000)
sage: %time a = m.identity_matrix()
CPU times: user 0.04 s, sys: 0.00 s, total: 0.04 s
Wall time: 0.04 s
sage: %time b = a.transpose()
CPU times: user 0.05 s, sys: 0.01 s, total: 0.06 s
Wall time: 0.06 s
}}}
