Bonjour,
( Compte tenu de la nature du message du posteur original, je ne crois
pas contrevenir à la netiquette en répondant en français, malgré que
ce soit un forum anglais.
Does anyone have any recommendations for an undergraduate Fourier analysis
book? In particular, does anyone know of any open-source or affordable books
that could naturally incorporate Sage? I'm asking for a colleague of mine.

OK, I use SAGE in my teaching a lot now. Its great for algebra, trig,
precalc, plots in 2D and 3D, limits, derivatives and integrals both
analytic and numerical.

You can use
sage: v = vector([1,2,3])
sage: w = vector([1,1,-4])
sage: w.dot_product(v)
-9
sage: w.norm()
3*sqrt(2)
etc. Just see http://www.sagemath.org/doc/tutorial/tour_linalg.html
for more examples.

Even easier is w*v (which defaults to the dot product for vectors).

Well, that was easy! So are these SAGE objects that you have to
construct? Its not clear where this code comes from. Is it a python
object, is it from maxima, gap, what?
Still, these constructs do not preserve the matrix paradigm from
MATLAB. For example, in MATLAB you can pass a matrix as
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.

Is there a way to do something like m.map(sin)? Should ther

That's it. Not sure why I didn't see that. Sorry for the noise.
