----------------------------+-----------------------------------------------
Reporter: jason | Owner: was
Type: enhancement | Status: new
Priority: major | Milestone: sage-3.1.3
Component: linear algebra | Keywords:

{{{
[05:16] <mabshoff> One thing we should definitely do is to have some
infrastructure to give a vector or matrix and check if all values are
without $foo in some norm to a given vector or matrix
[05:16] <jason-> like numpy.allclose?
[05:17] <jason-> but that doesn't use norms
[05:17] <jason-> it just compares entry-wise
[05:17] <mabshoff> Well, we can do entry by entry or some vector/matrix
norm.
[05:17] <jason-> well, you can't choose the norm.
[05:17] <mabshoff> the numpy.allclose would work in most cases, but we are
mathematicians :)
[05:17] <mabshoff> So using a norm is natural IMHO
[05:18] <jason-> so matrix.is_close(other_matrix, norm='blah')
