unwanted variable can I not assign

Hi, some function in matlab like "size" has options to give 2 outputs like "[a1,a2]=size(x)". But sometimes I don't want to waste space for another variable, is it possible to not do that?

If you don't want every answer from function just type "~" instead of variable.

Example:

[~,a2]=size(x)
