Base functions used by the L-BFGS-B routine.

Functions

get_bounds(x0, bounds)	Return the lower and upper bounds arrays.
is_any_inf(arrs)	Return whether any of the values in the given arrays is inf.
clip2bounds(x0, lb, ub)	Impose the bounds to x0.
count_var_at_bounds(x, lb, ub)	Count the number of variables exactly at the bounds.
projgr(x, grad, lb, ub)	Computes the infinity norm of the projected gradient.
display_start(epsmch, n, m, nvar_at_b, iprint)	Display information at solver start.
display_iter(niter, sbgnrm, f, iprint[, logger])	Display the objective function and the projected gradient for the iteration.
display_results(n_iterations, max_iter, x, ...)	Display the optimization results on the fly.
