Is vaderSentimentScores available in R2019a

Hi

I am trying to apply vader sentiment score following this link.

But, after executing the program for a string, I found this error,

vaderSentimentScores('i am a boy')
Undefined function or variable 'vaderSentimentScores'.

Is the function available in matlabr2019a?

It is not possible to install the MATLAB R2019b routine in R2019a. See though my reference to routines you can call from MATLAB.

No, it was introduced in R2019b.

See https://github.com/cjhutto/vaderSentiment for python library and https://github.com/nunoachenriques/vader-sentiment-analysis for a Java port of it. You can call Python or Java from MATLAB.

Walter Hi

Would you please advice me how could I call the setup.py( from the python library link you sent) from the Matlab?

Would it be like this?

str = 'python /dir/setup.py 2';
 [status, commandOut] = system(commandStr);
