function H = compute_directional_kernel(sigma1,sigma2,theta,nmax)

% compute_directional_kernel - compute oriented gaussian.
%
% h = compute_directional_kernel(s1,s2,t,nmax);
%
%   s1 is variance along first axis in pixels.
%   s2 is variance along secong axis.
%   t is the angle.
%   nmax is the maxium size of the kernel (optional).
