MATLAB Undefined function 'strsplit' for input arguments of type 'char'.

I encountered the following error in MATLAB:

Undefined function 'strsplit' for input arguments of type 'char'.

This is because the function strsplit() was only added in R2013a, and any earlier versions. Instead I used the textscan() function, and set the 'delimeter' parameter to the character I wanted to split the string by.
