B=histeq(A);

subplot(3,3,1);               %subplotting original Image

imshow(A);                

title('Original image'); 

subplot(3,3,2);

imhist(A);

title('Histogram of Original Image');     

subplot(3,3,3);

imshow(B);

title('Equalized Image');    

subplot(3,3,4);                   

imhist(B);

title('Equalized Histogram');
