I am using MATLAB version 2018b. I have the Computer Vision Toolbox installed as confirmed by using the ver command. However, upon using the following code:
hhoughtrans = vision.HoughTransform(pi/360,'ThetaRhoOutputPort', true);
I receive the following error message: Undefined variable "vision" or class "vision.HoughTransform".
Similarly, when using:
hhoughlines = vision.HoughLines('SineComputation','Trigonometric function');
I receive: Undefined variable "vision" or class "vision.HoughLines".
My conclusion is that vision.HoughTransform and vision.HoughLines are no longer supported though I haven't seen anywhere something to the contrary. Is this conclusion correct or could there be another issue?

Hmm. It's doing the same thing for me. The release notes states that they planned on removing this at some point:
But yet I still see it mentioned in Fixed Point Deisgner in 18b so there's a bug somewhere, doc or otherwise.

Do you have the computer vision system toolbox installed and licensed?
