Hi all,

I have a code which uses a hash defined like this :

$matrix[$x][$y][$z]

where x, y and z run from 0 to N (each).
Does someone know how to print all elements of "MATRIX" in a single
line (separated by a single space and all numbers formatted by %15.6F)
but looping over indexes z, y and x, respectively ?

In Fortran this is trivial :

WRITE(*,'(8000000E15.6)') (((matrix(x,y,z),x=0,N),y=0,N),z=0,N)

since the outer loop is Z, followed by Y and X.

I can't figure it out how to do the same in Perl.

Thank you in advance for any insights !

S.

Problem solved.

(it was not a hash but a multi dimensional array)
