function Y = qfft2(X, A, L)
% QFFT2 Discrete 2D quaternion Fourier transform.
%
% This function calculates the fast quaternion 2D Fourier transform of X.
% The second parameter, A, specifies the transform axis (that is the
% direction in 3-space of the vector part of the hypercomplex exponential).
% It must be a pure quaternion (real or complex) but it need not have unit
% modulus. L specifies whether the quaternion exponential is on the left
% ('L') or right ('R').
