Directory dependency graph for util:

Files
	auglag.h
	Augmented Lagrangian method for equality- and inequality-constrained minimization, with line/util/neldermead.h or line/util/levmar.h as the inner unconstrained solver.
	decimal.h
	Decimal literal -> T, without a detour through double when T is exact.
	eig.h
	Eigenvalues and singular values, backed by LAPACK.
	error.h
	The exception types the port throws.
	expm.h
	Matrix exponential by scaling and squaring with a diagonal Pade approximant.
	fdlibm.h
	The fdlibm elementary functions Java specifies, reproduced, for the code paths whose whole purpose is to land on the same bits as a Java reference.
	fft.h
	Discrete Fourier transform of arbitrary length, in double complex.
	http.h
	Minimal HTTP/1.1 client, enough to talk to a line-*-rest service.
	levmar.h
	Levenberg-Marquardt for nonlinear least squares.
	linalg.h
	Dense linear algebra over the templated number type: products, identity, inverse, and powers.
	line_console.h
	Running progress log of a LINE solver run (the "solver console").
	lp_highs.h
	A sparse LP backend for line::lp::LpModel, on HiGHS (MIT).
	lsoda.h
	LSODA: the LINE-facing wrapper over the vendored solver in third_party/lsoda.hpp.
	lstsq.h
	Least squares for a rectangular system, exact-capable.
	lu.h
	LU factorization with partial pivoting, templated on the number type.
	matrix.h
	Dense matrix and non-owning view.
	method_type.h
	Classification of a solution method, as printed in the solver banner: "<accuracy>, <randomness>" with accuracy in {exact, approximate, bound} and randomness in {deterministic, randomized}.
	neldermead.h
	Derivative-free simplex minimization (Nelder and Mead, 1965), with optional box bounds imposed by a change of variables.
	ode.h
	Adaptive stiff ODE integrator: a four-stage Rosenbrock method of order four with an embedded order-three estimate for step-size control.
	population.h
	Population-vector enumeration and combinatorics.
	rng_ssj.h
	The two random number generators the Java LDES engine draws from, reproduced exactly: SSJ's MRG32k3a and java.util.Random.
	rootfind.h
	Deterministic scalar root finding.
	simplex.h
	Templated primal simplex with Bland's rule.
	subprocess.h
	Running an external command and capturing its output, with a deadline.
	svd.h
	Singular value decomposition WITH the singular vectors, and the Moore-Penrose pseudo-inverse built from it.
	sylvester.h
	The Sylvester equation A X + X B = C, and MATLAB's lyap(A,B,C).
	tempdir.h
	A scratch directory for the subprocess wrappers, the port's lineTempName.
	websocket.h
	Minimal RFC 6455 WebSocket server, enough to serve LineWebSocketServer's protocol.
	xml.h
	A minimal XML DOM: read for the .lqnx interchange format, write for the JMT .jsimg and .jmva model files.
