function Y = qfft(X, A, L)
% QFFT Discrete quaternion Fourier transform.
%
% This function calculates the fast quaternion Fourier transform of
% (columns of) X. 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').
