Thanks for your response. I now do the following:
MS=MatrixSpace(ComplexField(),2,2)
A=MS(0)
A[1,1]=5
I was hoping I wouldn't need to make that many changes to the python
code, but this would seem to indicate Sage and Python aren't 1-to-1.
Unless I'm doing something very wrong, this question can

Hello. I'm a new user to Sage. I am trying to create a matrix without
knowing the values when it is initialized. All the examples I see have
static matrices like
A = matrix(QQ,2,2,[2,1,1,2])
My goal is to create a 2x2 matrix which I can then give values for
later
A[1][1]=5
However, I am told the ve

I'm forwarding your message to the sage-support list

can probably get more help. I have some comments but others may also be

Sage is known to start up quite slowly on some hardware/software.
I personally find it takes o

I fully agree with you. But it will not certainly give all prime ideals!

hi all,
I don't usually use the notebook very much, but now i sometimes do,
for various reasons. I am desperately missing one thing, and i hope
it's just that i don't know the keyboard shortcut for it : how do i
produce the same result as pressing the UP arrow in a terminal? I
mean, bringing back
Hello, I usually run "sage --notebook" from bashrun (an app launcher);
the fact is I don't do it from a terminal.
So, how should I quit? I can't find a way from the browser to quit, and
I have to open a terminal, "htop", and kill one by one the processes.
I could of course just launch from a term
Hi list,
I'm not sure about the behavior of the hermite_form() function of an
integer matrix.
As far as I know the Hermeiteform H of a given matrix A, it is a unique
(up to reordering of the rows and columns) triangular matrix (with some
extra conditions) wich could be obtained by A * U = H for som
17 matches
