undefined function or method 'unit8' for input argument of type 'double'

Answer 1

[Steven Lord]

To convert to an unsigned 8 bit integer use "uint8" not "unit8". Note the difference in spelling.

[John D'Errico]

I've seen this error many times in questions, including this same error made by me. My guess is that the fingers (and your brain) automatically want to type the word unit, not uint.

[Sean de Wolski]

I've done this at least high in the two digits, possibly low three digits number of times.

Though it looks like autocorrect picks up on it now :)

Why yes, I did!

[Adam]

Yes, I have done that countless times too, although I always hit the up-arrow too quickly to correct my mistake before realising Matlab did it for me and then I can't retrieve the correction with a down-arrow again :(
