Yes. mkdir()

if ~exist(folderName, 'dir')
    mkdir(folderName);
end

MATLAB: Create new folders by mkdir()

MAX_FOLDER_NUMBER = 10;
FOLDER_ROOT_NAME = 'folder';
for n = 1:MAX_FOLDER_NUMBER
    folder_name = [FOLDER_ROOT_NAME,sprintf('%d',n)];
    if not(exist(folder_name,'dir'))
        mkdir(folder_name)
    end
end

I tried to be very explicit about what each step is about. Also, this code checks whether the folder exists, but I don't actually think that is necessary. I don't think mkdir does anything if you try to create a directory that already exists, so you could just do

MAX_FOLDER_NUMBER = 10;
FOLDER_ROOT_NAME = 'folder';
for n = 1:MAX_FOLDER_NUMBER
    mkdir([FOLDER_ROOT_NAME,sprintf('%d',n)])
end

or just

for n = 1:10
    mkdir(['folder',sprintf('%d',n)])
end

if you don't want my parameterization.

MATLAB: Rename jpg files in a folder

Try this:

folder = pwd; % Wherever your input images are stored.
outputFolder = fullfile(folder, '/renamed'); % Can be the same as the input folder if you want.
% Make output folder if it exists.
if ~isfolder(outputFolder)
	mkdir(outputFolder)
end
fileList = dir('*.bmp')
% Loop over all files.
for k = 1 : length(fileList)
	% Get this filename.
	thisFileName = fullfile(fileList(k).folder, fileList(k).name);
	% Find out just the base filename without the folder.
	[~, baseFileNameNoExt, ext] = fileparts(thisFileName);
	number = str2double(baseFileNameNoExt);
	% Skip non-numbers
	if isnan(number)
		continue;
	end
	fprintf('Processing %s...\n', thisFileName);
	
	% Optionally display the image
% 	% Read in the input image.
% 	originalImage = imread(thisFileName);
% 	% Display it.
% 	imshow(originalImage);
% 	drawnow;
	% Create the new base filename without the folder.
	baseOutputFileName = sprintf('%3.3d%s', number, ext);
	% Create output image filename....
	fprintf('   Renaming to %s to %s...\n', baseFileNameNoExt, baseOutputFileName);
	% Create the output filename which will be in the output folder.
	outputFileName = fullfile(outputFolder, baseOutputFileName);
 	movefile(thisFileName, outputFileName); % or imwrite()
end
message = sprintf('Done processing %d images', length(fileList))
uiwait(helpdlg(message));

If you want to save the renamed files in a different folder, use imwrite(), otherwise if you want to rename in the same folder use movefile().
