% WRITE    Output a quaternion array to a text file.

% write(filename, format, a)
%
% This function writes a text file which is designed to be easily
% read into other software, such as Maple, Mathematica, etc.  The
% first line of the file contains two integer values giving the
% number of rows and columns in the file.  The quaternion values
% then follow in raster order, that is with the column index varying
% most rapidly. Each quaternion value occupies one line in the file,
% and consists of four floating-point values, separated by spaces.
%
% The format parameter may be omitted, in which case a default is
% assumed which outputs sufficient digits to represent double values
% with no loss of accuracy. Otherwise the format is a string (see the
% standard Matlab function fprintf for details).
%
% If the parameter a is a pure quaternion, only three components are
% written per quaternion.
