Undefined variable "vision" or class "vision.HoughTransform".

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?

Thuis is the output of ver:

So I have it installed. I presume it is licensed given I have a license or are these different things?

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?

Thanks for the information Sean. I'll just use hough instead.
