. The elements of the matrix
{en,m : n=0..(N-1)}
form a vector in the output space which is parallel to the displacement
caused by a small change in the m'th ordinate in the input space.
For example, if the input dimension is 4 and the
output dimension is 3, then a small displacement
(x0, x1, x2, x3)
in the input space will result in a displacement
(y0, y1, y2)
in the output space computed as below (en,m
are the matrix's elements):
[ y0 ] [ e00 e01 e02 e03 ] [ x0 ] [ y1 ] = [ e10 e11 e12 e13 ] [ x1 ] [ y2 ] [ e20 e21 e22 e23 ] [ x2 ] [ x3 ]
