Here's my solution, slightly simplified.

The data:
my %vars = (
 name => "Curve Matrix."
 ,matrix => [
 [ 0 , 365 , 1095 , 1825 , 3650 , 2555 ]
 ,[2.3 , 0.142 , 0 , 0 , 0 , 0 ]
 ,[2.4 , 0 , 1.72 , 0 , 0 , 1.71 ]
 ,[2.5 , 0 , 0 , 1.75 , 1.90 , 0 ]
 ]
 );

The template:
[% FOREACH line = matrix -%]
[%- line.join(',') %]
[% END -%]

The output:
0,365,1095,1825,3650,2555
2.3,0.142,0,0,0,0
2.4,0,1.72,0,0,1.71
2.5,0,0,1.75,1.9,0

I suppose, if you wanted to format individual values, you could do this:
[% FOREACH line = matrix -%]
[% FOREACH item = line -%]
[%- item %][% UNLESS loop.last; ","; ELSE; "\n"; END %][% END -%]
[% END -%]
