How to save Histogram of Multiple Images

clc; clear all; close all
folder = 'E:\input';
filepattern = fullfile(folder, '*.png');
srcFiles = dir(filepattern);
numImages = length(srcFiles);
for k = 1 : numImages
	fullFileName = fullfile(folder, srcFiles(k).name);
    I=imread(fullFileName);
    imhist(I);
    
    mkdir('E:\hist');
    path='E:\hist\img';
    
saveas(gcf,['histo' num2str(k) '.png'])
end

This is not working well. any help ???

This should be a start

sourcefolder = 'E:\input';
filepattern = fullfile(sourcefolder, '*.png');

% this shouldn't be in the loop 
% the subdirectory needs to exist before you use it
outputfolder = './hist/img';
mkdir(outputfolder);

srcFiles = dir(filepattern);
numImages = length(srcFiles);
for k = 1 : numImages
    % build full file path+name
    % use sprintf and zero-padded numbers (this assumes 3 digits is enough)
    inputfilename = fullfile(sourcefolder, srcFiles(k).name);
    outputfilename = fullfile(outputfolder, sprintf('histo_%03d.png',k));
    
    I = imread(inputfilename);
    imhist(I);
    
    saveas(gcf,outputfilename)
end
