Yes. Try readmatrix

myImage = readmatrix('my image.xlsx');
imshow(myImage);

If that doesn't work, try xlsread() or attach your workbook.

thank you for answer.

it's okay, but if i want for example to display the image in color, xlsread() does it automatically ?

Because i just have a grey image, and in my excel file i have color.

and is it possible, to display the values ​​of R, G and B in any position on the image and save them ?

You'd have to extract the R, G, and B parts of the matrix and then combine them. Like let's say the R, G, and B images were side by side in your workbook. Then you'd do

[rows, columns] = size(myImage);
columns1 = columns/3;
r = myImage(:, 1:columns1);
g = myImage(:, columns1 + 1 : 2*columns1);
b = myImage(:, 2*columns1+1:end);
rgbImage = uint8(cat(3, r, g, b)); % Or uint16 whatever you're using.

right after you call imshow(), call impixelinfo()

hp = impixelinfo;

If you want to reposition it, you can use

hp.Units = 'normalized';
hp.Position = [x, y, .2, .03]; % All values in the range 0-1.
