Returns an approximate minimum of the expression F with respect to the variables X, subject to an optional set of constraints. Y is a list of initial guesses for X.
F must be an ordinary expressions, not names of functions or lambda expressions.
optional_args represents additional arguments, specified as
symbol = value. The optional arguments recognized are:
constraintsList of inequality and equality constraints that must be satisfied by X.
The inequality constraints must be actual inequalities of the form
g(X) >= h(X) or g(X) <= h(X). The
equality constraints must be of the form g(X) = h(X).
rhobegInitial value of the internal RHO variable which controls the size of simplex. (Defaults to 1.0)
rhoendThe desired final value rho parameter. It is approximately the accuracy in the variables. (Defaults to 1d-6.)
iprintVerbose output level. (Defaults to 0)
maxfunThe maximum number of function evaluations. (Defaults to 1000).
On return, a vector is given:
var = value for each of the
variables listed in X.
load("fmin_cobyla") loads this function.
This function is identical to fmin_cobyla, except that bigfloat
operations are used, and the default value for rhoend is
10^(fpprec/2).
See fmin_cobyla for more information.
load("fmin_cobyla") loads this function.
