Hello all,
Per my earlier question in http://www.mathworks.com/matlabcentral/answers/252008-a-simpler-way-of-doing-a-nested-loop
Is there a way to generalize that nested loop so that it works for any sizes of h1? Thank you.

coeffs = [0.3, 0.2, 0.5, 0.8, 0.1, 0.75]; %for example
V = [1+1i +1-1i -1+1i -1-1i];
n = length(coeffs);
[Vg{1:n}] = ndgrid(V);
Vm = cell2mat( cellfun(@(C) C(:), Vg, 'Uniform', 0) );
t_h1 = Vm * coeffs(:);
h1 = reshape(t_h1, length(V) * ones(1,n));
clear n Vg Vm t_h1

@Mnr: try this:
V = [1+1i,+1-1i,-1+1i,-1-1i];
W = [0.3,0.2,0.5,0.8];
N = numel(V);
X = cell(1,N);
[X{:}] = ndgrid(V);
Y = cat(N+1,X{:});
S = [ones(1,N),N];
Z = sum(bsxfun(@times,reshape(W,S),Y),N+1);
