How to compare variables without if statement

I'm looking to verify that two variables produce the same (or different, then an error will occur) result. I'm looking to find a quick way to do this without utilizing if statements.

>> assert(3==4,'Mismatch')
Mismatch
>> assert(3==3,'Mismatch')
>>
ADDENDUM:
Of course, you can make things more interesting by wrapping the assert inside a try...catch construct...
>> a=3;b=4; % unequal variables
>> try
assert(a==b,'') % check equality, no message output
catch
disp('Unequal') % do whatever on error here
end
Unequal
>>
Of course, what this gains over simply writing a straightforward if...else...end construct is difficult to see without context.

What's to explain?
> help assert
assert Generate an error when a condition is violated.
assert(EXPRESSION) evaluates EXPRESSION and, if it is false, displays the
error message 'Assertion Failed'.
assert(EXPRESSION, ERRMSG) evaluates EXPRESSION and, if it is false,
displays the character vector contained in ERRMSG. ...
See the doc for all the gory details.
You gave no klews as to what you expect to be able to do...
