[sage-support] matrix log?
Does sage have built-in the analog of MatrixLog in Mathematica? I noticed that one can use logm in scipy: from scipy import linalg matrix(linalg.logm(mat)) (where mat is the matrix whose log is to be computed), but I am wondering whether there is a better way?

Ok. Having a public cloud file seems like good solution.

I'm not sure what you mean; usually the easiest thing to do to upgrade Sage is either 1) download a new binary manually and just use that one, since the metadata is not in the Sage binary 2) recompile a Sage you have already built from scratch by pulling from the latest git repository Also, though I am scared to try this nowadays, 3) In theory I think "sage -upgrade" still works... I bet the answer depends slightly on this - for instance, 1) shouldn't be a firewall problem at all since you are asking for it? Anyway, I hope someone answers this because we should add it to the installation guide and download webpage - which both seem to advocate for 3) without mentioning firewalls. -- You received this message because you are subscribed to the Google Groups "sage-support" group.

But there is then the barrier of having to use the cloud - which, no offense, is still ridiculously long to log in and use things on even in high bandwidth situations. It's fine for actually getting work done once you are in, but not for quick and low-barrier sharing of ideas. After all, many people are probably creating things in their *local* Sage installations and then would want to share without having to make a special public cloud thing. Along those lines, as far as I know there are some scripts to sanitize all sagenb.org published worksheets. Please someone with the know-how find a way to put as many of these, even in text-only mode, somewhere - it was SUCH a valuable resource, and I really do feel that people looking for Sage examples and help (both in research and in teaching) have been stymied by the lack of this searchable resource. You all know I would do it in a minute if I had the background but admin stuff is not something I have any experience with. But this is a special case for you all because it only has to be done once, and then is basically just a bunch of HTML files to keep served, just disable/strip out js etc. (Perhaps they could be scripted into a special cloud project that is all public, bringing more interested visitors there... just sayin'.) - kcrisman -- You received this message because you are subscribed to the Google Groups "sage-support" group.

Well, in Maxima there is mat_function, e.g.:
load ("diag");
mat_function (log, mymatrix);
For large, numerical matrices, I'm sure linalg.logm is much faster.
But for small or nonnumerical matrices, maybe Maxima is useful.
Hope this helps,

Another issue that I recently fixed was that many of the webserver VM's were being swapped out by Linux when they weren't being actively used, so people visiting the site might randomly hit a slow VM, which would take minute or two to become fast. Over the weekend I eliminated all use of swap by everything in the SMC stack, which has removed this problem.

I'm just saying that it isn't always my experience, and it depends a lot on one's bandwidth situation. Even just now while logging in was usably fast (first time ever! but likely due to your upgrades) it took about 10 seconds for an actual project to load each time. And then one has to open a worksheet, or whatever. That is good for lots and lots of use cases, but maybe not for *all* use cases. And I have spent a lot of time the past three months teaching Sage in situations where the bandwidth to Seattle I have at home right now would have been really nice to have, quite so.
