Read the error message. It tells you what the problem is. Did you check the class name?

You mispelled 'uint8'

@Joe Joe

in your code mat= zeros(250, 250, 'unit8')

please remove that unit 8 term and the code will run without any errors.

[Karthik Bhogi]

you can also use 'single' or 'double' in place of 'unit8' to run your code without any errors.
