Unable to to use image processing tools

Hi there,

When I try to use something like:

imrotate or imtool

in matlab 2015b, it gives me the following error:

Undefined function or variable 'imrotate'
Undefined function or variable 'imtool'

Because I was very desperate to find the solution, I researched a bit about this problem and also tried

>> which imtool
'imtool' not found.

I am still stuck and have no idea what to do.

One last thing I tried was the following:

>> license('test','image_toolbox')

ans =

       1

>> addpath(genpath([matlabroot '\toolbox\images\']))
>> savepath
Warning: Unable to save path to file 'C:\Program
Files\MATLAB\R2015b\toolbox\local\pathdef.m'. You can
save your path to a different location by calling
SAVEPATH with an input argument that specifies the full
path. For MATLAB to use that path in future sessions,
save the path to 'pathdef.m' in your MATLAB startup
folder. 
> In savepath (line 204)

Also, when I tried changing the path to say desktop, I kept getting the same warning. Can someone please help? What am I doing wrong? How do I solve this!

Thanks

Looks like the license is valid but for some reason the toolbox is not installed. Maybe you installed a trial over it that didn't have it. Regardless, you should call the Mathworks on the telephone. Believe it or not, this is your fastest route to a solution. And it's FREE. All installation solutions are free. Do it now so you'll have it ready before they close for the day.
