how to access the outputs seperately?

suppose i have a function f(x) =@(t) sim(net,t'). It has 2 outputs how can i seperate them? example: f(1) = [1,2], f(2) =[3,4], f(3) = [5,6] .... then how can i call only 1st outputs of the above results (i.e, {1,3,5 etc}) i hope that i was able to explain my problem, looking forward for an answer.

Assign them to a variable and index them.

Or if you really want to do it in an expression, define an anonymous function such as

Col1 = @(V) V(:,1);

and then you can code things like

f = @(t) Col1(sim(net,t'));

thanks for the reply. if i write "col1=@(v) v(1,:)" and then use "f=@(t) col1(sim(net,t'))", then am i calling first row?

[Walter Roberson]

Yes if you used @(v) v(1,:) that would get the first row, and I would suggest you name it appropriately such as row1 instead of col1 (column 1).

Be aware that you asked for the routine to work on [1 2]. That is a row vector, so the first row of it would be identical to the vector. If you want the 1 part, that is column 1 of the vector, not row 1 of the vector.

Thank you for your reply, it was just an instantaneous example provided by me for explaining the question clearly.
