Hi!
It looked an easy thing to me but no solution is working in loading a .txt file in MATLAB. I cannot understand why?. The .txt file consists of depth values from kinect camera and separated by a space.
I have tried all the functions in MATLAB for the same but everytime I get a blank variable in which I am trying to load the .txt file.
The .txt file has been attached here. It would be great if somebody who knows this can help me out here.
Thanks in advance!

USER111 = load('USER-1-1-1.txt');
imagesc(USER111)

If you try working with the floating point values up to 2047, it is easy to get into situations where MATLAB does not treat your data the way you think it should be treated. You might want to convert it:
img = mat2gray(USER111); %will return values in the range 0 to 1

Try using load() function and convert it to scaled image using imagesc().
Data = load('USER-1-1-1.txt');
imagesc(Data);
