Restore previous working directory on MATLAB Startup

This simple program will restore the last working directory on resuming MATLAB

Description

This simple program will remember your last working directory and will prompt you on resuming MATLAB, whether the user wants to start in the last working directory or not  
Just copy the contents of the zip file in the Matlabroot work directory  
ex: c:\Matlab\R2006b\work and make sure that its on the path.  
i.e type path on MATLAB command prompt and see if the above directory exists in the path. If the "work" directory does not exist on your path, then use the "pathtool" function to add the work directory manually.

• MATLAB release: MATLAB 7.3 (R2006b)
• Other Files: finish.m, ; startup.m

[Andreas Köhler]

I made the following modification to finish.m such that my startup.m - which already contains important data - is not overwritten: 
 
%%%%%%% finish.m %%%%%% 
str = pwd;%store present working directory in the variable str 
 
% figure out where to put restorewd script 
pathstr=userpath; 
if(isempty(pathstr)) 
  pathstr=[matlabroot filesep 'work']; 
else 
  pathstr=pathstr(1:find(pathstr==pathsep)-1); 
end 
 
fid = fopen(fullfile(pathstr,'restorewd.m'),'wt');%open file for writing 
fprintf(fid,'answer = questdlg(''Do you want to continue working in the previous working directory'',''Restore Last Working Directory'',''Yes'',''No'',''Default'');\n');%write this and the following 3 lines into restorewd.m 
fprintf(fid,'cd(''%s'');\n',str); 
fprintf(fid,'end'); 
fclose(fid);%close file 
%fprintf(fid,'end'); 
fclose(fid);%close file 
 
 
Now, create or append to your existing startup.m: 
 
if exist('restorewd')==2 
  restorewd 
end
