man gbnlmult (1): Solve systems of non linear simultaneous equations

SYNOPSIS

gbnlmult [options] <function definition>

DESCRIPTION

Least square estimation of a system of j non linear equations. Read data in columns (X_1 .. X_N). The j-th equation is specified by a function f_j(x1,x2...) using variables names x1,x2,..,xN for the first, second...N-th column of data. The f_j(x1,x2,...)'s are assumed i.i.d. according to a multivariate gaussian distribution.
