Simple Use of Strings

I am simply trying to get through a Tutorial online and am having a problem running a simple string. It is returning the error:Undefined function 'string' for input arguments of type 'char'.

I am typing: >> a = string('Hi how are you') Undefined function 'string' for input arguments of type 'char'.

This is my first time using MatLab. Do I have to engage this feature to use it? I am pretty sure I have it typed in correctly.

What release of MATLAB are you using? If you're not sure, look at the output of the ver function.

I am using version 2016a which answers the question. I did find that by typing in:

a={'Hello' 'Goodbye'; 'Yes' 'No'; 'what are you doing' 'by the way'}

it seems to solve the same function. What is the difference?

Different classes of data:

a = {...} % cell array
b = "..." % string

Some functions accept inputs arguments of different classes, some don't. It depends on the function.

By the way, the best place to start to learn MATLAB is here:

Your version of MATLAB does not support the string class.

"String arrays were introduced in R2016b":
