What does ~ mean in the case of an if statement?

This one appears to be ungoogleable due to the short length of the character.

Take for example...

if ~isempty([stats.Area])

Does this mean the equivalent of a 'not' function? Ie in this case it would be if the area array is not empty do something?

Thanks in advance.

It means "not". Basically it's saying that if stats.Area is not empty (in other words, it has values), then do something.

It means not(your expression')

Exemple

a=[1 0]
~a

or

not(a)
