MATLAB: Matrix (Resultant from an Expression) Indexing

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)
?

Best Answer

  • Yes
    A = randn(20,10);
    size(A,2)
    size(A,1)
    So
    N = size(A,2);
