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].
