How can I put two noises in an image?

-my code(diagonal noise)-

clc


k=imread('clue.jpg');
k=rgb2gray(k);
k=double(k);

[x,y]=meshgrid(1:512,1:512);
p=1+sin(x+y);
tp=(k/128+p)/4;
imshow(tp)

-my code(Vertical noise)-

clc

k=imread('clue.jpg');
k=rgb2gray(k);
k=double(k);


sig=30/255;
k(:,:) = k(:,:)/255;
for i=1:3:512
    y=randn;
    k(:,i) = k(:,i) + sig*y;
end

imshow(k)

I want to put these two noises in one image.

What should I do?

How about

imshow((tp+k)/2)
