SIZE()

[Angus]

SIZE(M) returns a list which contains the dimension of Matrix M.
When M is a vector SIZE() returns a list with one value? Is that a bug? I mean if M:=[1,2,3,4,5] SIZE(M) should be {1,5} and not {5}. How would I distinguish a vector from a matrix I think that is inconsistant. Or am I missing something?

Thank you!


edit: the promblem came up in a small program where I want to use SIZE(M1) as an integer value. No success. I then played with size in the homescreen like in the attachement.




update: using length() works, but as i understood length writen in small letters is cas command. And SIZE is home command and should be priorized.
And in home the question remains.
