Is it possible to compare individual values of two vectors without a for loop?

a & b are string vectors of 1 x 2,000,000
c is an empty integer vector of 1 x 2,000,000
Using for loops, my code is thus:
for i = 1:2000000
if a(1,i) == b(1,i)
c(1,i) = 1;
else
c(1,i) = 0;
end
end
This is a simple example of what I'm trying to accomplish, but I'm looking for a faster way to do this and I don't know how to 'vectorize' comparisons.

a="abc";
b="Abc";
c=char(a)==char(b)
