in the following code i wanted to use gray image which saved in variable b for further use,but it gives an error "undefined b" on second line... kindly sort this out
CODE:
i=imread('C:\Users\Romesha\Desktop\eye.jpg');
b=rgb2gray(i);
imshow(b);
im = imread(b);
imshow(im);

Good catch, Bruno. I got sidetracked by the "undefined b".
But to be more correct, you can use a variable in imread(), but it needs to be a variable that contains a string. For example,
F = 'C:\Users\Romesha\Desktop\eye.jpg';
im = imread(F);
