31 /* Levenberg-Marquardt minimization. */
40 * in n variables by a modified Levenberg-Marquardt algorithm.
41 * The function evaluation is done by the user-provided routine 'evaluate'.
42 * The Jacobian is then calculated by a forward-difference approximation.
48 * x is the solution vector (INPUT/OUTPUT, array of length n).
55 * data is a pointer that is ignored by lmmin; it is however forwarded
56 * to the user-supplied functions evaluate and printout.
59 * evaluate is a user-supplied function that calculates the m functions.
61 * n, x, m, data as above.
63 * m function values for the parameter vector x.
