I'm trying to solve a system of non-linear equations that involves logarithms of several variables. I have developed code in another system to do so using the function lsqnonlin. Is there an equivalent function in Mathematica 7? I need to input the function matrix, the initial approximation vector, and the precision and get a vector with the solution values of the variables. I don't seem to find anything by searching on the web. Thank you
