how to convert 5 dcm images to 5 png images

Hi all, i have 5 dicom images. i want to convert it to png images.

clc
clear all

% Get a list of all files in the folder with the desired file name pattern.
myFolder = 'C:\Users\Akmal\Documents\MATLAB\Add-Ons\Functions\Region Growing\ct koh';
filePattern = fullfile(myFolder, '*.dcm'); % Change to whatever pattern you need.
theFiles = dir(filePattern);
for L = 1 : length(theFiles)
    baseFileName = theFiles(L).name;
    fullFileName = fullfile(theFiles(L).folder, baseFileName);
    fprintf(1, 'Now reading %s\n', fullFileName);
    % Now do whatever you want with this file name,
    % such as reading it in as an image array with imread()
       RZ(:,:,L)= dicomread(fullFileName);
       
end
% [RZ, map] =  dicomread(fullFileName);
       RZ11(:,:,L) = im2uint16(RZ(:,:,L) );


dcmImagei(:,:,L)  = uint8(255 * mat2gray(  RZ11(:,:,L) )); 
imwrite(dcmImagei(:,:,L),'qqqmyGray.png');

BUT MY PROBLEM IS JUST ONE IMAGE PRODUCE. HOW ABOUT TO PRODUCE ANOTHER 4?

clc; clear all; close all;
% Get a list of all files in the folder with the desired file name pattern.
myFolder = 'C:\Users\Akmal\Documents\MATLAB\Add-Ons\Functions\Region Growing\ct koh';
filePattern = fullfile(myFolder, '*.dcm'); % Change to whatever pattern you need.
theFiles = dir(filePattern);
for L = 1 : length(theFiles)
    baseFileName = theFiles(L).name;
    fullFileName = fullfile(theFiles(L).folder, baseFileName);
    fprintf(1, 'Now reading %s\n', fullFileName);
    % Now do whatever you want with this file name,
    % such as reading it in as an image array with imread()
    RZ(:,:,L)= dicomread(fullFileName);
    RZ11(:,:,L) = im2uint16(RZ(:,:,L) );
    dcmImagei(:,:,L)  = uint8(255 * mat2gray(  RZ11(:,:,L) ));
    imwrite(dcmImagei(:,:,L), sprintf('qqqmyGray%d.png', L));
end
