Hi. I am trying to read in images from a set of sub directories. I first need to list all directories off my main directories (called newpath). I do this by:
cd(newpath)
p=dir *c*
This generates a list of subdirectoires. Becasue I want to plot the mean of the directories in order, I need to resort the list. At the moment C1.1 is first, then C10.1 etc. I need C1.1, C2.1, C3.1 etc.
Any ideas please?
C1.1 C113.1 C128.1 C142.1 C157.1 C171.1 C186.1 C20.1 C214.1 C229.1 C243.1 C258.1 C272.1 C287.1 C300.1 C43.1 C58.1 C72.1 C87.1
C10.1 C114.1 C129.1 C143.1 C158.1 C172.1 C187.1 C200.1 C215.1 C23.1 C244.1 C259.1 C273.1 C288.1 C301.1 C44.1 C59.1 C73.1 C88.1
C100.1 C115.1 C13.1 C144.1 C159.1 C173.1 C188.1 C201.1 C216.1 C230.1 C245.1 C26.1 C274.1 C289.1 C302.1 C45.1 C6.1 C74.1 C89.1
C101.1 C116.1 C130.1 C145.1 C16.1 C174.1 C189.1 C202.1 C217.1 C231.1 C246.1 C260.1 C275.1 C29.1 C31.1 C46.1 C60.1 C75.1 C9.1

Have a look at Natural-Order Filename Sort.
BTW, you don't need to change the directory. Just use
d = dir(fullfile(newpath, '*c*'));

Stephen's submission is probably fine, maybe better. The one before it, from Doug Schwarz, is http://blogs.mathworks.com/pick/2006/09/11/file1-file10-file2-sorting-problem-solved/
By the way Jason, you might also want to look at genpath(), maybe not for this case, but it's good to know about, and is needed in some cases, such as if you want to recursively go into all subdirectories looking for more subdirectories, like my attached demo does.
