What about this one:
http://www.sagenb.org/home/pub/1839
where I solve ax=b for x where a is a 2x2 matrix and b is 2x1 so x is
2x1.
My question is, what if I want to solve the same system of equations as
xa=b where a is 2x2 and b is 1x2 so x should be 1x2?
BTW, now that I have my matrix al
Yes, I did try all this in SAGE successfully based on your help! Thanx
so much! Please see my recent posts for published worksheets showing
my attempts

Have you tried doing all of these in Sage? The syntax below (except for
the matrix creation) should work just fine. I presume you've already
tried finding the answers in the documentation---if the documentation is

That's it. Not sure why I didn't see that. Sorry for the noise.
Maybe because it started with "apply", which isn't exactly the most
obvious word when you are looking for this option. It would be nice to

Is there a way to do something like m.map(sin)? Should ther
Jorge,
vector and matrix objects as described here are Sage constructions.
Behind the scenes different packages might do the computations (such
as numpy).
I don't know MATLAB, but here's a way to square every entry of a
matrix ("process the data"). Might be an easier way that I don't
know.
