Undefined function or variable error
显示 更早的评论
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
ver

On my system I get
> which psnr
/Applications/MATLAB_R2015b.app/toolbox/images/images/psnr.m
Have you checked that at the image toolbox is included in your path using path?
And if so, does the directory contains all the files, in particular psnr.m?
And if so, that you have read permission for that file?
ls -l /Applications/MATLAB_R2015b.app/toolbox/images/images/psnr.m
should give something starting with
-r--r--r-- 1

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.
