Image processing toolbox not working
显示 更早的评论
Hello,
I installed matlab with the image processing toolbox, but it doesn't work.
When I try to use the toolbox's functions matlab can't find them:
>> dicomread
Undefined function or variable 'dicomread'.
The ver command doesn't show the imaging toolbox as being installed:
-----------------------------------------------------------------------------------------------------
MATLAB Version 9.5 (R2018b)
Simulink Version 9.2 (R2018b)
RF Toolbox Version 3.5 (R2018b)
Signal Processing Toolbox Version 8.1 (R2018b)
Statistics and Machine Learning Toolbox Version 11.4 (R2018b)
Symbolic Math Toolbox Version 8.2 (R2018b)
However, the license command tells me the opposite.
>> license('test', 'image_toolbox')
ans =
1
>> license('checkout','image_toolbox')
ans =
1
Thanks for your help.

As far as MATLAB can tell you have the toolbox licensed but not installed.

The add-on explorer shows that it's installed:

Do you mind to restart your matlab or restart your computer and try that again?

The image shows you have Image Processing Toolbox installed in R2020b, but your ver shows you are using R2018b
