% rotate manually

% get the current view (azimuth, elevation)
[az,el] = view

% explicitly set the view
view(-35,40);  % lh
view( 35,40);  % rh

% define 3-element vector with [A E R]
% where A is azimuth
%       E is elevation
%       R is image rotation (positive means clockwise)
oo = [-35 40 0];  % lh
oo = [ 35 40 0];  % rh

% after you carefully decide on your parameters,
% the code (cvn functions) need to be modified
% accordingly.

% the relevant functions are:
