- Subject: unflattening fortran matrices
It appears that gfortran is going to be poorly vectorized
due to the use of a flat representation of multidimensional
matrices. Has any thought been given to creating a branch to
begin work on conversion to a non-flat matrix representation?
Also how common is it among fortran compilers to use a
flat representation for matrices?
