 than one dimension.
Every array of more than one dimension has correspoiding one dimensional
vector that holds the entire elements linearly.
This vector is obtained by the <B>array-entity</B> macro.
Also, note that a two-dimensional matrix should be transposed
if it is sent to the FORTRAN subroutines, since rows and columns
are ordered oppositely in FORTRAN.

<P>
Since EusLisp's representation of floating-point numbers is always single
precision, conversion is required when you pass a vector of double prec
