using fsolve with arrays

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

What happens instead of it working ?

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.
