Note that KSSV's answer actually counts the total contents of a folder, including any files.

As Walter Roberson wrote in that last link: "In short: if your code assumes that '.' and '..' are the first two entries in a directory, your code has a bug (even in MS Windows). If your code assumes that directory entries are returned in any sorted order, your code has a bug (in all OS.)"

go the folder...and use
k = dir ;
N = length(k)-2 ;
N should be the number of sub folders.

This answer also includes any files. So I don't think it is the answer

The correct answer would be something like this:
P = 'absolute or relative path to the folder';
S = dir(P);
N = nnz(~ismember({S.name},{'.','..'})&[S.isdir])
