[Ferenc Nagy]

The original Prolog used to have only lists. Matrices could be handled as lists of lists. Binaries appeared later. Now the array2M class makes easy the programming of matrix operations and translating linear algebra subroutines from Fortran and other languages.

Is there anybody on the list who has experience in this topic, e.g. who applied a matrix inversion subroutine to VIP7 using two dimensional array?

Frank,
I have not used array2M for matrix operations in the way you suggest, but I have used it as a 2-dimensional buffer of identity key values in an ODBC application that speeds up data access by a factor of more than 10! And I love it.
