# Solver for multiple variable

I have a function which depends of multiple parameters, and I need to find the parameters that minimize some error function.

Is non linear, but works well with conjugate gradient and central derivative methods on other software, which just do not have the necessary precision.

Is there something similar in PariGP?

The "solver" function seems to work only with one parameter.

Please, do not ask for more specific details about the function. This is a general question.
