There's no operator that I know of
Dear Sage community,
Is there a possibility/workaround in Sage to compute the element-wise
multiplication of two matrices? In Matlab there's the .* operator, but
Matlab is useless in my case since I need a symbolic result.
Thanks in advance for every help

I am running into problems using the gcd function in sage. (version
3.4.2)
Specifically, I am iterating over a set of integers [a,b,c,r,s,t]
which I want to be coprime. I check this using gcd([a,b,c,r,s,t]). The
problem is that it returns 1 for tuples that should not have gcd = 1.
For example, fo

This works:
sage: n=6
sage: R=PolynomialRing(QQ,n,'z')
sage: z=R.gens()
sage: g=sum(z[i] for i in range(n))
sage: g.subs(dict((z[i], i) for i in range(n)))

My turn to say sorry. I just mentally wiped out the '.subs' part.

When I say that n is not predetermined, I mean that I want my script
to work for any n. So before I define the polynomial ring, n is
determined, but I want this to work for all n. So my question is how
do I do the following.
n=6
R=PolynomialRing(QQ,n,'z')
z=R.gens()
g=sum(z[i] for i in range(n)
sorry, i meant
g.subs({z[1]:value1...})
I am not sure why you call this intriguing syntax, but it is what
works.
Example:
g=x+y
g.subs({x:2,y:4})
6
My problem is that I don't know how to do this if the number of
variables is not predetermined.
I tried to make a list with
a=list()
for i in rang

I want to substitute n values into polynomial with n variables.
I guess the syntax to do this is (if g is my polynomial with
indeterminates z[1], ..., z[n]).
f.subs({z[1]:value1, z[2]:value2, ..., z[n]:valuen})
but how do I actually do this? n is not set, so I just can't type
this out.

Hi all:
Upon upgrading to Sage 4.0, i can no longer make a dictionary with
derivatives as keys (see below). Can someone please fix this?
