I am trying to create folders using mkdir, but if I have already created that folder, how do I check that before creating it. a = mkdir(directorylocation,text1) returns 1 in variable a if the directorylocation\text1 is created and if the directory exists. What is the function or condition that checks whether directorylocation\text1 exists

well, I suppose you want to create if it doesn't exist, after checking... so you could do it like that:
if ~exist(yourFolder, 'dir')
mkdir(yourFolder)
end
It basically check if youFolder does not exist. If that's true, it creates youFolder.
Cheers.

if not(isfolder(yourFolder))
mkdir(yourFolder)
end

In case anyone else was wondering why this solution is better:
To check the existence of a file or folder, you also can use the isfolder or isfile functions. exist searches for files and folders on the search path, which can lead to unexpected results. isfolder and isfile search for files or folders only on the specified path or in the current folder, which can lead to clearer and faster results.
