MATLAB: Undefined function or variable ‘extractBetween’.

extractbetweenfunctionnot foundundefinedvariable

I use Matlab 2016 and when I try the following command I get this error:

list = extractBetween(html,’<h3 class=”” title=’,’</a></h3><p>’);
Undefined function or variable 'extractBetween'.

I also searched in help but I got:

extractbetweenextractbetween not found.

What is the problem and how can I fix?

M - Which version of MATLAB are you using? It could be that your version of MATLAB is too old to support this function. See https://www.mathworks.com/matlabcentral/answers/276377-why-want-the-code-generation-examples-open#answer_215823 for details.

You can check to see if the function does exist by typing the following at the command line

 which openExample

and it will return either the path to the function or something like

 'openExample' not found.

(which it does for me with my R2014a).
