I hope to create such custom function
function addnum(mat,n=numel(mat))
mat+n
I mean I try to add a number into the element of mtrix mat,but if I don't give a explicit value for n,I hope the n will be the number of the mtrix self.

function addnum(mat) mat + numel(mat) ; can't this work for you? – Siva Srinivas Kolukula Jul 17 '17 at 06:16

@rahnema1 Oh,actually not,my this default `n` vale linked the first parameter `mat` – yode Jul 17 '17 at 06:26

@yode There is no difference. Such a syntax is not acceptable in MATLAB, however Octave accept it. – rahnema1 Jul 17 '17 at 06:27

@SivaSrinivasKolukula Thanks man,but I hope `addnum(mat,3)` works either,then every element will add 3. :) – yode Jul 17 '17 at 06:29

Yes it adds 3 always....as the input is 3. – Siva Srinivas Kolukula Jul 17 '17 at 06:35

As this answer,this is what I'm after
function addnum1(mat,n)
if nargin<2
n=numel(mat);
end
mat + n
