So here's perhaps where my knowledge of "practical Fortran" is limited.
I know you can operate very easily of arrays in F90, but I didn't know
that an expression like for instance A*B for two two-dimensional arrays
A and B really corresponded to a matrix multiplication. Please enlighten me!

A*B performs element-wise multiplication, and matmul(A,B) does matrix
multiplication. One can define operators so that A .x. B performs
matrix multiplication.
