Dyadic (Two-Argument) Form:
Reshape
(Structure) A p B
The
reshape
function forms
an
array of the shape specified
by
argument A
using
element(s) from argument
B.
The elements of argument B are placed into the
array
in
row
order.
If
there are not enough elements
in
argument B
to
fill
the
array, the elements are repeated.
If
there are more elements
in
argument B than
are required to
fill
the array, only the required number of elements are used.
Argument A must
be
a nonnegative integer or vector of nonnegative integers. The
number
of
elements
in
argument A
is
equal to the number of coordinates, or the
rank, of the result. Argument B can
be
any variable or constant.
If
all
of the
elements of argument A are nonzero, then B cannot
be
an
empty array:
