I = imread('camera man.png');

R = I(:)';

x=0.3;

p=0.343;

for n=2:65536;

if x(n-1)>=0 & x(n-1)<=p

x(n)=x(n-1)/p;

else

x(n)=(1-x(n-1))/(1-p);

end

A=sort(x);

[A,T]=sort(x);

Y=R(T);

C=reshape(Y,[256,256]);

V=imshow(C);

D=C(:)';

[D,U]=sort(T);

M=Y(U);

F=reshape(M,[256,256]);

imshow(F)

i want to check the key space nd key sensitivity . plz help
