Not exactly sure what you're looking for but you might look at the functions contains() and strfind():

str = 'Arizona'; % Arizona is awesome!  And it contains both upper and lower case A.
containsA = contains(str, 'A', 'IgnoreCase', true)
containsQ = contains(str, 'Q', 'IgnoreCase', true)
logicalA = str == 'A' % Case sensitive.
logicalQ = str == 'Q' % Case sensitive.
ALocation = strfind(str, 'A')
QLocation = strfind(str, 'Q')

In the command window, you'll see:

containsA =

logical

1

containsQ =

logical

0

logicalA =

1×7 logical array

1 0 0 0 0 0 0

logicalQ =

1×7 logical array

0 0 0 0 0 0 0

ALocation =

1

QLocation =

[]

So, does one of these do what you want? Any follow up questions?
