Hi There
I have been using MATLAB R2016a version for a while , it is working perfectly but i need to activate it monthly , I observe undefined function error or variable during my work even though i am sure about the work space and the typed command
for example when i write any command with psnr or immse , it gives me the mentioned error
it was working previously but now i do not know why ?
Kind Regards, Ayidh

Both commands are part of the image processing toolbox. Maybe you have not installed this toolbox in your current version? To check what is installed, type

i tried to type which psnr and immse , it seems my version have no license avaliable for
C:\Program Files\MATLAB\R2016a\toolbox\images\images\psnr.m % Has no license available Trial>> which immse C:\Program Files\MATLAB\R2016a\toolbox\images\images\immse.m % Has no license available
so is there any way to solve that or i have to get a version which is not trial
thanks

If you have a trial version you should have asked for all at the toolboxes you need. Otherwise you get only the basic Matlab without any toolboxes.
