I would like to display a matrix as an image. The matrix is of size 250 2. I used image() function. But got an error stating an error.
CIJ=cell2mat(Cipher);
kk=CIJ*(1/100);
Cipher is of size 250 2. I tried to display kk, but I got a blue image. It must be a black and white image know? How to solve this issue?
