Set variable equal to folder in path

I am running a script in multiple directories. They are organized like this:

MainDir/SubDir1/SubDir2/AnalysisDir1

I want to store the string "SubDir1" as a variable, which I will later insert into the name of the output files.

Here's how I accomplish this in cygwin:

cd ./../../

SubDir1="${PWD##*/}"

cd ./SubDir2/AnalysisDir

Any help would be much appreciated.

Assuming you start off in MainDir:

S = 'SubDir1';
A = fullfile(pwd, S, 'SubDir2', 'AnalysisDir1');
fprintf('Changing directory to %s.\n', A)
cd(A)

Thanks for the code. I don’t think my question was clear. I don’t want to manually assign ‘Subdir’. I want the code to extract ‘Subdir’ from the existing path. Here is my list of Directories. Note that I changed “Subdir1” to “Subdir1a,b,c…”

MainDir/SubDir1a/SubDir2/AnalysisDir1

MainDir/SubDir1b/SubDir2/AnalysisDir2

MainDir/SubDir1c/SubDir2/AnalysisDir3 …

I will run the matlab file using a .bat file which I will use to run multiple different programs in series. For the Matlab portion of the .bat file, I will first change the working directory to the analysis directory (e.g. AnalysisDir1), and then I will run MatlabScript.m within the analysis directory.

I want to have lines of code within MatlabScript.m which will pull SubDir1a (or b,c, etc) out of the path, so that my output can be sent to SubDir1a.txt

Are there any other thoughts on this question? Thanks!
