Description (last modified by )
This ticket began with building an all-ones matrix constructor, as contained on the first patch. But that was already happening over on #9685.
New title, new decription, new patch are about adding onto the ones_matrix
constructor. Specifically,
- Significant additions to the documentation.
- Setting
nrows=None
in the function definition allows for a call with just a single integer entry, producing a square matrix over the integers, similar to the behavior foridentity_matrix
. Requires one new error-check.
- Isn't it better to coerce a generic 1 into the ring and then use that to populate the matrix? I've done that.

Replying to kcrisman:
Like the concept, don't like the
INPUT
block. Can you make it look more like the other ones, say in plotting - with bullet points and entry type and defaults, that is? At least, I think the current one won't look that nice.
Thanks, KDC. Was just too sloppy and forgot the bullets.
Tried to work on this and discovered a ones_matrix
constructor was merged into 4.6.1.alpha1 at #9685! Guess I was not paying attention as well, since it was over in "user interface." Looks like Robert Miller did like I did and cribbed from the zero_matrix
constructor, so I think there is not much difference between his and mine.
I do have an INPUT block in my documentation, even if it needs work. ;-) Should I steal from my work here and slightly improve the already-merged version? I've cc'ed the folks on the previous ticket.

Might as well do the same thing for the zero_matrix
et al. as well.
I see no reason why this ticket shouldn't be renamed to reflect this new purpose...
