Dear I am using R2017B with text analytics software installed(I have checked by searching get add-ons). I have written a simpole function which is following:
function x=test()
s='i am a boy and u r a grl';
disp(removeStopWords(s));
end
And it shows the following error:
Undefined function or variable 'removeStopWords'.
Would you please shed light on this issue explaining why is this happening?
Thanks,

So it appears that you have Text Analystics Toolbox so that best option is to contact Mathworks support team by pressing the Contact Us button on the on right corner of this page. They will guide you further.

removeStopWords does not work on strings or char vectors, only on tokenizedDocument.
The way MATLAB searches for functions means that it will only find removeStopWords if you have a tokenizedDocument in your workspace.
>> clear all
>> which removeStopWords
'removeStopWords' not found.
>> td = tokenizedDocument;
>> which removeStopWords
[..]/matlab/toolbox/textanalytics/textanalytics/tokenizedDocument.m % tokenizedDocument method
