Replace matlab function with user defined function in code

Hi, the existing function is as follows:

[a,e] = arburg(est_x1,PSam,k);

I would like to replace the arburg fucntion with the function in arburgw1.m in the code. How can I do that?

"How can I do that?"

x=r_t;     % !!! get rid of this line of code !!!
p=PSam;    % !!! get rid of this line of code !!!
function varargout= arburgw( x, p, ventana)
..
end

When you write code before the FUNCTION() definition then you are turning that Mfile into a script and you will not be able to call the function from anywhere else. If you want to be able call that function somewhere else, then do not turn the Mfile into a script.

thanks, how do i get [a,e] from this function?

[Zahrah Walid]

function [a,e]= arburgw( x, p, ventana)
..
end

Once you write a callable function (i.e not a script, as explained in my last comment), then you can simply call it with those output arguments, just as the introductory tutorials show:

[a_out,e_out] = arburgw1(..)

Note that you should replace the evil EVAL() with slightly more robust FEVAL().
