for example, if I had:
G1=(1:1:10)*0.181881788
G2=(1:1:10)*1.281888281
and I need to find where
sum(G1*sin(G2*x))=0
I tried
x=(fsolve(@(x)sum(G1*sin(G2*x)),cc))
where cc=(1:1:5)
but it doesn't work.
thanks

As G1 and G2 and x are vectors, you probably want G1 .* sin(G2 .* x)
otherwise it is going to try to do matrix multiplication and likely fail.
