  • ischar: Checks if an input is a character array.
  • iscellstr: Checks if an input is a cell array of strings.
  • isletter: Checks if each character of an input is a letter.
  • isspace: Checks if each character of an input is a whitespace character.
  • ispunctuation: Checks if each character of an input is a punctuation mark.
So isstring function is not a built-in string-checking function

Why don't you read the documentation? Or just try each of them? Or choose to *not* comment with an expletive...

I only ever use maybe two of these, but even still, there was prominent suspect in the lineup.

I must admit there are two I don't know. In the interest of fairness and honesty I will register my vote first and then check the documentation.
