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.
