How can I solve the following equations (given in the previous examples) without any initial guess?


y[0] = x[0] * x[1] * x[2] - 6;

y[1] = x[0] * x[0] * x[1] +
x[1] * x[1] * x[2] +
x[2] * x[2] * x[0] -
23;

y[2] = exp(x[0] + x[1] + x[2]) - 403;

Also, can you provide me an example how can I perform this with Fitmrq? Thanks!
