I have a gray scale image of Digital Surface Model (DSM). I tried to open it with imread() from image processing toolbox but it only shows me a white image. when I open the matrix of image I found the weird numbers as matrix arrays and I attach the example here. My question is why it happens and how can I solve it?
Thanks in advance.

clc clear all I = imread('DEM.tif'); figure, imshow(I)
these are the codes our image is float 32 and even when we want to convert the data type it is not showing any change.

What if you use imagesc to show your image? There might be a problem with the scaling of your image.
imagesc(I)

the problem is not related to scale as I think, we have problem with values of the image in the matrix, when we want to show it it only gives us white image or black.
