Problems using function fsolve

I'm trying to execute a fsolve function. First, I tried without using optimset and it went wrong because of maximum function evaluations and maximum iterations. So I rewrote the code as:
funm = @dissertacao_momento_funcao;
x0m = [1;1];
options = optimset('MaxFunEvals',1e5,'MaxIter',1e5);
xm = fsolve(funm,x0m,options);
But now it's returning the error below:
No solution found.
fsolve stopped because the relative size of the current step is less than the
default value of the step size tolerance squared, but the vector of function values
is not near zero as measured by the default value of the function tolerance.

I tried to set TolFun and TolX as 1e-15 but it didn't solve the problem. After I did it, it returned the same error and some of the times I ran the code it returned a different error:
No solution found.
fsolve stopped because the problem appears to be locally singular.

Can anybody help me, please?
