RESIZE RESIZE Resizing an Array

Usage

Arrays in FreeMat will resize themselves automatically
as required in order to accomodate assignments.  The rules
for resizing are as follows.  If an assignment is made to
an n-dimensional array (where n >= 2) that is outside the
current dimension bounds of the array, then the array is
zero padded until the it is large enough for the assignment
to work.  If the array is a scalar, and an assignment is 
made to the non-unity element, such as:

a = 1;
a(3) = 4;

then the result will be a row vector (in this case, of size 3).
Row and column vectors will be resized so as to preserve their
orientation.  And if an n-dimensional array is forced to resize
using the vector notation, then the result is a row vector.
