Solving nonlinear system using Fsolve function

Hello,

I am trying to solve for this system of nonlinear equations in matlab:

function f = nle(x)

x=x(1); y=x(2);

f(1)=((2.5+y-0.5*x)^.5)*(4-x)/b*((19.84+y-0.5*x)^0.5)-874.9837752; f(2)=((2.5+y-0.5*x)^.5)*d/(3-y)*((19.84+y-0.5*x)^0.5)-2558585887;

In the command window I type:

x0=[1 1] fsolve=('nle',xo)

and then I get an error that says:

??? Attempted to access x(2); index out of bounds because numel(x)=1.

Error in ==> nle at 4 y=x(2);

Error in ==> fsolve at 254 fuser = feval(funfcn{3},x,varargin{:});

Caused by: Failure in initial user-supplied objective function evaluation. FSOLVE cannot continue.

I do not understand what the error means. Someone Please help!!

Thank you

[Sean de Wolski]

x = x(1);
y = x(2)

you overwrite x by saying x = x(1)...
