Why mamfistype2 function is undefined?
显示 更早的评论
I run the function mamfistype2 according to https://uk.mathworks.com/help/fuzzy/mamfistype2.html.
fis = mamfistype2;
But this is what I get:
'Undefined function or variable 'mamfistype2'.
Does anyone know why this happen?

function mamfistype2 requires the Fuzzy Logic Toolbox. Run the following lines to check if the toolbox is installed
ver fuzzy
If you get the follow output, then you need to install the toolbox
Warning: No properly formatted Contents.m file was found for 'fuzzy'.

Fuzzy Logic Toolbox not being installed is one reason this class may not be available. It was introduced in release R2019b according to the note at the end of its documentation page, so if the user has an older release installed that would also explain why it is not available.
