I'd suggest you define a function called 'ocr' for input arguments of type 'unit8'.

We can't help you without knowledge of the ocr function.

The function ocr is part of the Computer Vision System Toolbox. In the Command Window type

 ver

to see your version of MATLAB and all installed toolboxes. Or, in the Command Window, type

 which ocr -all

to find the location of this function. If you don't have it or the toolbox, then you will need to purchase the latter.
