problems_i​n_using_no​minal

Hi

I have problemms in using nominal function; the error I get is that it is part of statistics and machine learning package.

I have earlier used nominal function on my previous computer , one year ago and cant understand why this is not possible now with the same licens as I had before.

Thanks

Muazma - please copy and paste the full error message to this question. It could be that the version of MATLAB on this new computer does not have the Statistics and Machine Learning Toolbox. See How can I see which toolboxes I have installed? on how to check for the presecnce of the toolbox.

[Muazma Ali]

i have tried using ver and licence('test', statistics_toolbox') which gave me zero.

the error I get working with datasets and nominal function says statistics and machine learning toolbox is required. i think it is strange since I have worked with datasets using the same licence for one year ago

Hi,

try the following workflow:

ver

the result should contain

...
Statistics and Machine Learning Toolbox               Version 11.3        (R2018a)
...

If not:

install the toolbox following these instructions:

https://de.mathworks.com/matlabcentral/answers/101885-how-do-i-install-additional-toolboxes-into-an-existing-installation-of-matlab

If yes:

try:

which nominal -all

Result should look somehow like this:

C:\Program Files\MATLAB\R2018a\toolbox\shared\statslib\@nominal\nominal.m  % nominal constructor

If the result looks like:

C:\Program Files\MATLAB\R2018a\toolbox\shared\statslib\@nominal\nominal.m  % nominal constructor
C:\Stephan\Matlab\projects\nominal.m                                          % Shadowed

you should rename the script in your working folder (here C:\Stephan\Matlab\projects\nominal.m)

If the result is empty:

install the toolbox again, following these instructions:

https://de.mathworks.com/matlabcentral/answers/101885-how-do-i-install-additional-toolboxes-into-an-existing-installation-of-matlab

Finally:

If you can not install the toolbox check your license here :

If you do not have a valid license for your release buy a license or install a Matlab release for which you are having a license for the toolbox.

If nothing helps at all:

it was almost empty i am uninstalling matlab 2018b again.

how can I know which release I have a valid licence for that toolbox?

[Stephan]

i do not know a smart way to do this. You can see the date when the maintainence service expired for this toolbox in your license details. The corresponding release i would expect to have the toolbox included.

[Stephan]

Since my license service expires in june 2019, the release R2019a will have all features, when i install it.

If i do not renew my licenses i will not be able to run R2019b. if i only buy some of the toolboxes in the future, i will only have access to all toolboxes i buy together with the new services. my R2019a will expire, but i can always use all toolboxes with this release.
