I think it's a file path problem, that's why I tried the file open
dialog. I took a look at my path:
'/sagenb/servers/sage_notebook-sagenb.sagenb/home/daldrich/24/data/'
But that's on the sagenb server. Is there a way to upload my csv?
That might make things simpler.

Why is it easier to decide if the items correspo
The difficulty with accepting an iterator (of strings) is that it is
unclear if each item corresponds to a row or an element. But I would
be in favor of rather liberal string parsing, so one could do
matrix(open("test.csv").read())
just like
matrix("""
1,2,3
4,5,5
""")

Thank you very much for that code. Just to clarify, I'm using the sage
notebook (running on my machine), will the code still work? I.e. be
able to read where the files are on my machine even when using the
notebook interface?
Thank you very much for your help.

You can already do:
sage: import csv
sage: M=matrix(RR,list(csv.reader(open("m.csv"))

Hi Harald,
You answered I should of phrased that question better, but lets say I
created a matrix in Sage, and I want to save it as a csv file how do I
do that?
The matrix is made from the following function below
Def function(A,D)
(syntex for making matrix P)
return P
Kind Regards

uhm, i'm not sure if you ask about reading or writing. also, your "d" in
