Hello,
I have a problem with this
(%i1) P: makelist(P[i], i, 1, 3);
(%o1) [P , P , P ]
1 2 3
(%i2) PP: diag_matrix(P);
(%o2) [ [P , P , P ] ]
[ 1 2 3 ]
This not create diagonal matrix as I need.
How to pass to "diag_matrix" as sequence with no list but simply as P[1],
P[2], P[3].
So I need list P without "[" and "]" i.e.
P[1], P[2], P[3]
but not in this form
[ P[1], P[2], P[3] ]
I need such list for e.g. 100 elements, so it is to hard to write it by hand
as
PP: diag_matrix(P[1], P[2], P[3], .... P[100])
I can use "diag" and it works with list P, but how to pass it to diag_matrix
as no list?
(%i3) load("diag");
(%o3) /usr/share/maxima/5.21.1/share/contrib/diag.mac
(%i4) PP2: diag(P);
[ P 0 0 ]
[ 1 ]
[ ]
(%o4) [ 0 P 0 ]
[ 2 ]
[ ]
[ 0 0 P ]
[ 3 ]
Thank you in advance,
Zbigniew
