[Matlab-emacs-discuss] run a cell in a script which contains a function

[Uwe Brauer]

Hi the following script (not live script) can be executed in the matlab
editor, just on a cell
%% 
A = [4,-2,-1,-1; -2,6,-2,-3; -1,-2,5,-1;-1,-3,-1,6]
x = [0;0;1;0]
[lambda,v] = eigs_potencia(A)
%% 
function [lambda, v] = eigs_potencia(A)
    [n,m] = size(A);
    tol = 10^-6;
    itermax = 50;
    iter = 1;
    v = rand(n,1);
    v = v/norm(v);
    w = [zeros(n,1)];
    while (norm(v-w)>tol & norm(v+w)>tol)
        w = v;
        z = A*v;
        lambda = transpose(v)*z;
        v = z/norm(z);
        iter = iter+1;
        if iter > itermax
            warning('se ha alcanzado el numero maximo de iteraciones')
            break
        end
    end
    lambda, v, iter
end



However the command matlab-shell-run-cell seems not to recognize the
function which is defined in the very same file.

I think that is now an important feature to support, because matlab
supports is also in the live scripts.

Not sure how difficult that would be to implement. Any comments?
