>> which im2single

C:\Program Files\MATLAB\R2016a\toolbox\images\images\im2single.m % Has no license available

But I do have the licence for image processing?!! is it not included?

[Adam]

So you need to have the license for the Image Processing toolbox.

ver will tell you what is installed, but not whether or not you have a license for those toolboxes. You'd need to check which toolboxes are on your license for that.
