Try the unit matrix.pp which is part of FPC's RTL. It also includes
overloaded operators if you need them. ^^
Afaik matrix only defines 4x4 or less.
Numlib also has a large number of matrix routines (including determinant,
eigen values etc), but is

2010/10/9 Bo Berglund bo.bergl...@gmail.com:
So I need to get hold of two Delphi functions:
function matmul(X, Y: array of double): array of double;
and
function transpose(X: array of double): array of double;
Where can I find such functions?
I am not a matematician myself so I don't know
You may want to look at the matrix.pp unit included in the rtl.
It contains many matrix operations.

FPC can generate the SSE instructions for you on compilation. My tests showed

They are available in a library named LAPACK. You can find downloads
by doing a Google search on this name. It is coded
