% Matlab/GNU Octave functions to calculate the maximum adirectional slope 
% as a function of baseline in a digital elevation model. This software is not official 
% and is provided 'as is'. Supported elevation models are HiRISE *.cub files, which are
% USGS ISIS3 cubes output from SOCET SET.
%

% USAGE
% -----
%   
% Example: Calculate adirectional slope maps at 10, 50 and 200 m baselines, at an 
% angular spacing of 10 degrees, for the DEM 'thisDEM.cub', which has spatial resolution 
% of 1.05 m. Save the results to 'thisDEM.mat'.
%
%     % Note that if res is passed as empty or zero then res is set to the 'pixres' value 
%     % in the header.
%     fpath = 'thisDEM.cub';
%     outfpath = 'thisDEM.mat';
%     L = [10 50 200];
%     res = 1.05;
%	  alpha = 10;
%     success = calcAdirSlope(fpath, outfpath, L, res, alpha);
%
% The amount of memory depends heavily on the size of the DEM. Observed memory 
% consumption for typical HiRISE DEMs ranges between ~15 - 40 GB. It is recommended to 
% run this code on a sufficiently capable system.
