string comparison comparison

Hi,

I have two string variables, say,

var1 = 'sale';
var2 = 'none';

When asking whether var1 is NOT equal to var2, I want matlab to confirm
the answer that var1 is indeed not equal to var2. In other words, I
want the variable "ans" to be 1 instead of 0 from the following lines:

if var1 ~= var2,
ans = 1;
else
ans = 0;
end;

However, Matlab returns ans = 0. I think it is because:

» var1 == var2
ans =
0 0 0 1

So that the assertation that var1 ~= var2 is not entirely true.
Nevertheless, is there anyway to let Matlab understand that I want to
compare the entire word rather than the letters? Thanks in advance.
