I have searched the usual channels and not found an answer. I am trying to access functions in the Image Processing Toolbox but they are undefined.
Other answers on here have led me to do some checks and I have found:
1) The toolbox is installed.
2) I have a licence for it (through my university) and I am logged into my account. I have checked this by looking at the toolboxes included as part of my university licence as well as checking from the command window using --- license checkout Image_Toolbox --- and received ans = 1
3) The addon is enabled.
I have also checked for and run updates.
