In Matlab or C , when comparing strings which are just arrays of characters you should always use the strcmp string compare function. Do Not. Strings are arrays of characters. We often use them to represent information to the user of our programs. Sometimes we use them to store information about the state of our program. When we do so, we will often want to "test" this state.

The input arguments can be any combination of string arrays, character vectors, and cell arrays of character vectors. Find the word 'upon' in a cell array of character vectors. There is only one occurrence of s1 in array s2 , and it occurs at element s2 1,2. There are three instances of equal elements in s1 and s2.
