I have a string that is going to keep updating
Say x='ear' how do I take the last later in the string so say lastletter='r' is it possible to have this work generally to always take the last later in a the string so say x gets updated to 'eart' lastletter=-t'

x = 'ear';
lastletter = x(end);

AllA = x(x == "a")
I have not tested this, just a belief this works

No that would not work. When you use == to compare a character vector to a string scalar, the character vector gets converted to a string scalar and then the == would be comparing for string equality not character equality.
On the other hand
x(x == 'a')
would pull out all of letter 'a'
