Thread Subject: how to creat directory name

hi guys,
I faced a problem about creating a directory and saving figures in it. and I need the directory name which changes with my input values N. I did this as follows, but it doesn't work.


N = 10;
directoryName = sprintf('%dGammaFigure',N);
if ~exist(directoryName,'dir')
    mkdir(directoryName)
end
paths=[pwd,'\directoryName\'];% problem comes here,directoryName is not 10GammaFigure but is directoryName itself

x = 0:0.01:1;
y = exp(x);

plot(y,x);
set(gcf,'PaperPositionMode','auto');
print('-djpeg', [paths,'figure.jpg']);

Please help me to solve it. thanks

This does not make much sense. You created a variable called, say z, and
then you expect this variable to have its original value when you typed it
inside a string as in `\z\` ??

Why not simply create the directory name with those slashes on it in the
first place?

EDU>> N=10; directoryName = sprintf('\\%dGammaFigure\\',N);
EDU>> paths=[pwd,directoryName]

paths =

C:\Documents and Settings\Owner\My Documents\MATLAB\10GammaFigure\
