string function not found

Question

i have a cell array defined as

class = {'good','bad','good','bad','good','bad','good','bad'};

and i am trying to create a string array from this cell array and hence i use the function class = string(class) but i am getting this error

Undefined function 'string' for input arguments of type 'cell'.

and I am assuming this could just be because of the version of my MATLAB provided by the university does not have this function installed but is there anyway to solve this problem?

Which version of Matlab are you using? If you use its installed help then you will know if string exists as it will have a help page. Unless you have a very recent version it won't though.

What does

which string

show?

Given that you are overwriting the function 'class' with a variable name (never a good idea) you may well also have a variable called 'string' somewhere.
