I am translating a bunch of Fortran functions to FPC and I
have now come across a problem with a couple of built-in
Fortran90 functions:
MATMUL multiplies two matrices (arrays) and returns the result.
TRANSPOSE reorders the array elemsnts in some predefined way.
The call in the Fortran routine is like this:
b = matmul(transpose(a), a)
where a and b are equal sized dynamic arrays of double.
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 what these
functions really do...
Try the unit matrix.pp which is part of FPC's RTL. It also includes
overloaded operators if you need them. ^^
(In Lazarus: enter the unit name in the uses clause and do a Ctrl+left
mouse button on it to view its contents)
