This is nice, but i have to define vector of possible theta, this is not what i want to do. I have vector of unknow parameters theta. I have som estimate of theta, but i want to do better estimate of them, using some criterion function. I mean it is clasical argmin f(x_1,x_2,...x_n) to fit vector (x_1,x_2...,x_n)`
