I'm relatively new to MATLAB and am working through some examples. I have not been able to get this example to work. The error that keeps getting returned is Undefined function 'ocr' for input arguments of type 'uint8'. Error in ocrExample (line 11) ocrResults = ocr(businessCard); So far I have: * Double checked that I have version 2014a. * Ensured I'm typing into a script (not the command window). * Made sure I have the Image Processing and Computer Vision add-on installed. * imshow('businessCard.png') returns the image, so it's not an image location issue. Could anyone offer some assistance?

OCR function undefined in 2014a?

The error that keeps getting returned is

   Undefined function 'ocr' for input arguments of type 'uint8'.
   Error in ocrExample (line 11)
   ocrResults     = ocr(businessCard);

So far I have:

Double checked that I have version 2014a.
Ensured I'm typing into a script (not the command window).
Made sure I have the Image Processing and Computer Vision add-on installed.
imshow('businessCard.png') returns the image, so it's not an image location issue.

This may occur if the Computer Vision System Toolbox is not installed. Type out VER in the MATLAB Command Prompt and see if you find this toolbox listed.
