function dpsssave(N,W) 
% A simple utility function to calculate dpss and save them to disk 
% with filename and format as used by the various mtm routines. 
%  
% Alternatively, a script something like the following could be 
% used to totally automate the process - run this one overnight 
% if you are going to compute many large dpss! 
% 
% cd e:\matlab\mtm    % Substitute your desired directory here. 
% [E,V]=dpsscalc(256,2);   save s256_2.mat 
% [E,V]=dpsscalc(256,5/2); save s256_25.mat 
% [E,V]=dpsscalc(256,3);   save s256_3.mat 
% [E,V]=dpsscalc(256,7/2); save s256_35.mat 
% [E,V]=dpsscalc(512,2);   save s512_2.mat 
% [E,V]=dpsscalc(512,5/2); save s512_25.mat 
% [E,V]=dpsscalc(512,3);   save s512_3.mat 
% [E,V]=dpsscalc(512,7/2); save s512_35.mat 
% 
% etc., etc.
