[sage-support] Re: Using elements from matrix in equation?
2016-01-01 15:29:20 -0800 (PST), Nils Bruin: You are correct: AC is a 2-by-1 matrix, and AC[0] selects the first row. > You can select the appropriate elements via > > a = AC[0,0] > b = AC[1,0] > > or > > a = AC[0][0] > b = AC[1][0] > I would recommend the first syntax, a = AC[0,0] which just accesses the given element, and so it is faster than a = AC[0][0] which would create the vector AC[0] and then get its index 0 coordinate. Moreover, if you want to change an element of a matrix, writing AC[0,0] = 9 will work, while AC[0][0] = 9 will fail. -- You received this message because you are subscribed to the Google Groups "sage-support" group.

[sage-support] Re: ERR_CONTENT_LENGTH_MISMATCH: SageMathCell Minimum Requirements
No idea, but the configuration of public servers is mostly public as well at
https://github.com/sagemath/sagecell/tree/master/contrib/vm
(what is missing are details of handling SSL certificates and some "high
level" network adjustments for particular configuration - I highly doubt
they can cause subtle issues like yours)

I confess I did not see this issue before, but I have basically only binaries from rpm packages installed in my computer. I also usually have latest sagemath installed in my home directory, to make some comparisons/tests with the rpm package. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
