How to automate a process?

• Note: English is not my first language and I may be not very explicit.

I have the input data:- matrix A(3,2)=[683265.032 465089.623; 683248.660 464977.521; 683303.746 465039.114].

     -_Function ,,Orientation"_ which contains this formula: *atan((B(1,2)-A(1,2))/(B(1,1)-A(1,1)))*200/pi*.

And this matrix B(3,3)-output data: B=[-1 Orientation(A(1,:),A(2,:)) Orientation(A(1,:),A(3,:)); Orientation(A(2,:),A(1,:)) -1 Orientation(A(2,:),A(3,:)); Orientation(A(3,:),A(1,:)) Orientation(A(3,:),A(2,:)) -1];

• "-1" means that Orientation to the same point can't be calculated.

So far so good by now. But what if I want to add 2 more rows of coordinates in matrix A? I want matrix B to calculate, using function "Orientation", regardless of how many sets of coordinates matrix A contains (rows). I don't want to write manually the commands in B every time I add new data to A. It is possible to automate this process?

The question is not clear. Are the functions "Orientation" and "Orientare" identical?

Yes they are. Sorry, my mistake

I do not understand the question completely. Perhaps you are looking for:

function R = Orientation(A, B)
R = atan((B(:, 2) - A(:, 2)) ./ (B(:,1) - A(:,1))) * (200/pi);

In my example i have A(3,2) and the calculated matrix B(3,3) with the function Orientation. I want to make matrix B to be calculated regardless of number of lines that matrix A have.

for A(n,2) I want B(n,n) to be calculated with that function
