I want to form a set of function handles in a row matrix.
i wrote script like below.
w = 2;
Nr = 20
nr = @(phi)zeros(1, Nr);
wr = @(phi)zeros(1, Nr);
for n = 1:Nr
for i = 1:w
Awr = 50*(cos(i*2)-cos(i*9));
nr(1, n) = @(phi)nr(1, n)+Awr*cos(i*1.7);
end
wr(1, n) = @(phi)nr(1, n)
end
Iam getting the below error
Nonscalar arrays of function handles are not allowed; use cell arrays instead.
how to rectify this??

MATLAB used to allow nonscalar arrays of function handles, but that functionality was removed probably 10 to 15 years ago. As the error message suggested, store your function handles in a cell array instead.

@Bathala Teja: function handles cannot be multiplied (or have any numeric operation applied to them). But you can certainly evaluate the function handles (just as Steven Lord showed) and multiply their outputs:
f{1}(3)*f{2}(3)
% ^^^ ^^^ Evaluate!
