CHECKVARS

Checks for function masking by variables in an M-File.

CHECKVARS(FILENAME) reads the M-File FILENAME and looks at all variables used inside. Then a check is made to see if any of these variables are possibly masking another function on the path. If conflicts are found, a description of each one is printed to the command window. [V,L] = CHECKVARS(FILENAME) also returns all variables V used in the file. L has the line number for each variable.

One fun thing is to do this:

D = dir([matlabroot,'\toolbox\matlab']);
p = pwd;

for jj = 3:length(D)
try
cd([matlabroot,'\toolbox\matlab\',D(jj).name]);
catch
continue
end

fprintf('\t\t\t In directory: %s\n',D(jj).name)
M = dir('*.m');
cd(p)

for ii = 1:length(M)
fprintf('%s\n',M(ii).name);
checkvars(M(ii).name);
fprintf('\n')
end
end

String manipulation has never been my strong suit, so if there are simplifications which could be made I would appreciate an email showing me where. Also, if a bug is found please email me to let me know about it. Thanks.
