hi
i want to remove 150 words from 2226 texts (1x150 and 1x2226 matrixes)
i googled it and this came up
https://www.mathworks.com/help/textanalytics/ref/tokenizeddocument.removewords.html#mw_a8ddd2cf-21eb-4d3f-b921-c8e5cf7a2404
this is the code: newDocuments = removeWords(documents,words)
but when i use it in matlab it says: Undefined function or variable 'removeWords'.
i also cant find it on my matlabs search tab
is this for another version?
is there another code?
if not can you help me pelase

As the link indicates by containing the folder "textanalytics", this is a function in the <Text Analytics Toolbox>
You must have a license for the Toolbox to use the function.
You can do such operations with the builtin string handling functions; if we had actual sample of your dataset would be far easier to suggest specific code for the purpose.

Ran in:
str1 = 'Hello world, how are you?' ;
str2 = 'how are you?' ;
str=setdiff(strsplit(str1),strsplit(str2))
str = 1×2 cell array
{'Hello'} {'world,'}
