Matrix (Resultant from an Expression) Indexing

Say I want to get the length of an array A . Normally I would do:

[m,n]=size(A)

And then use the n in other expressions.

But what if I want to get my n immediately; is there anything of the form

n=size(A)(2)

analogous to how I would pull the second element n from an array N using

n=N(2)

?

Yes

A = randn(20,10);
size(A,2)
size(A,1)

So

N = size(A,2);

Did you read the help?

Thank you. I did read the help, but it seems not attentively enough.

Am I assuming similar functions will follow the same pattern f(A,n) , where n is [1 to max size of the output array].

yes
