What is the current directory when the program runs? Which directory did you try to create using MKDIR and has it been successful?
Please try:
disp(cd)
fileattrib(cd)
% To my surprice "UserWrite: 0" does *not* mean, that
% I cannot create a file in the directory?!
imwrite(rand(100, 100, 3), 'test.jpg', 'jpg');
[Succ, Msg] = mkdir('coding');
if Succ ~= 1, error(Msg); end
imwrite(rand(100, 100, 3), ...
fullfile(cd, 'coding', 'test.jpg'), 'jpg');

Are you using Windows 7 by chance? You may be running into conflict with the Windows 7 Index function. Fairly detailed instructions for turning it off are here.
