The FORTRAN language allows you to add and subtract arrays using whole arrays as in the statement

C = A + B

Standard FORTRAN also provides a function called MATMUL to multiply arrays.

For matrix inversion you will need a third party library such as LAPACK. You don't get this with FTN95/Plato. Here is a reference...
