Lets say that we have a 256x256 double image, how can we convert it into a 256x256 uint8?

Actually, very few of us here are MathWorks employees. Most of us (including me) are unpaid volunteers who do our individual and collective best to share what we know.
If you cannot get im2unit8 or uint8 working, contact MathWorks Tech Support to see if they can figure out what the problem is.

My pleasure!
I wish we could have gotten im2uint8 or uint8 working for you.

There is no function 'im2unit8' but there is a function im2uint8. It matters how you spell it and you spelled it incorrectly. I never use it - I use uint8(). im2uint8() also does scaling, of course you could use uint8(mat2gray()) to scale it to the full range.

I misspelled it in my last Comment but not earlier. Waseem has it in his MATLAB search path but apparently can’t use it or uint8.
That seems to be the problem.

Waseem — You spelled it correctly earlier in this thread. However we did not see your code, so I assumed you simply misspelled it in your Question.
