How can I get Matlab to check for a specific string and show it's location?

Lets say I have the following:

A = [a1,a2,a3,a11,a22,a33]

When I say

Index = strfind(A,'a1')

Matlab tells me that there are 2 a1 because it considers the a11 as well. Same for a2 or a3.

How can I specify that I want a1 only.

I appriciate the help.

Surafel - use strcmp instead

>> A = {'a1','a2','a3','a11','a22','a33'};
>> result = strcmp(A,'a1')

result =

     1     0     0     0     0     0
