I have installed Computer Vision Toolbox and Image Processing Toolbox but I still get this error when I try and use createMat:
Unrecognized function or variable 'createMat'.
Error in opencv_tests (line 4)
[inputMat,inputArray] = createMat(img);
My code:
import clib.opencv.*;
import vision.opencv.util.*
img = imread("cakes.jpeg");
[ocvMat,ocvArray] = createMat(img);
Looks like it's not picking up the add ons?

Hi Malcolm,
You might also need to install the Add-on 'Computer Vision Toolbox Interface for OpenCV in MATLAB' to use the 'createMat' function. If you haven't installed it yet, please do so and try running the code again.
You can find more details about the 'createMat' funciton in the following documentation:

I hope this helps!

Awesome! That sorted it.
It's odd that this wasn't listed as a requirement - would have saved me a lot of head scratching.
Anyway, many thanks for your help.
