Why is 'cp_2-feb-2016_1' invalid string in MATLAB? I get:

>>  cp_2-feb-2016_1
  cp_2-feb-2016_1
               ↑
Error: The input character is not valid in MATLAB statements or
expressions.

where can I even read docs or how would/should I have googled/searched for this error?

Strings in Matlab must be surrounded by single quotes. For example:

>> 'cp_2-feb-2016_1'
ans =
cp_2-feb-2016_1
