MATLAB: Fsolve does not work anymore

fsolvematlab2013a

I tried to use fsolve in Matlab2013a, but it doesn't work anymore. Is is changed to fzero?
Here is my code:
x(:,1)=table(:,1);
x(:,2)=table(:,2)*10/60*2*pi;
x(:,3)=table(:,3)/100;
F=@(c)x(:,1).*x(:,2)./(c(1)*(x(:,1)/(3/2*1/2*c(2))).^2+x(:,2).*x(:,1)/(3/2*1/2))-x(:,3);
c0=[0.5,2];
options=optimset('Display','iter');
c1=fzero(F,c0,options);
But there is an error:
Error using fzero (line 233)
FZERO cannot continue because user supplied function_handle ==>
@(c)x(:,1).*x(:,2)./(c(1)*(x(:,1)/(3/2*1/2*c(2))).^2+x(:,2).*x(:,1)/(3/2*1/2))-x(:,3) 
failed with
the error below.
Attempted to access c(2); index out of bounds because numel(c)=1.
Error in twtable (line 82)
c1=fzero(F,c0,options);
What's going on here?
Thank you very much for your help!

If you no longer have the Optimization Toolbox, you can probably get away with FMINSEARCH instead, since it is only a 2-parameter problem
 c1 = fminsearch(@(c) norm(F(c)) , c0)
