BRAWLER Border Functions

These are generalized shape functions used throughout brawler to provide shapes used for value functions. These functions replicate BRAWLER v7.5 border.f

Border is a smooth step function transitioning at 0. The formula used for positive and negative arguments are designed to make border be continuous in first derivative at z=0. Also, border(z,z0) = 1-border(-z,z0).

Parameters

z	basic independent variable
z0	width-defining parameter

Returns: ranges from 0 for z < z0 to 1 for z > z0

double border (const double z, const double z0)

double cauchy (const double z, const double z0)

◆ tbl1b()

double BRAWLER::tbl1b	(	double	x,
		double *	z,
		int	nx,
		double	xmin,
		double	xmax )

Interpolates a one-dimensional lookup table. Used for evenly-spaced table case. Performs work that callers of param1 may need to perform in-line. This function replicates BRAWLER v7.5 tbl1b.f

Parameters

x	Real - independent variable
z	Array dim(nx) of real - tabulated dependent variable. The abstract result Z(X) is desired.
nx	int - Dimension of Z
xmin	Real - Z(1) corresponds to Z(XMIN)
xmax	Real - Z(NX) corresponds to Z(XMAX)

Returns: Interpolated Z(X). Values outside XMIN, XMAX are truncated.

◆ tbl2()

BRAWLER_EXPORT double BRAWLER::tbl2	(	double	x,
		double	y,
		double *	z,
		double *	xval,
		int	nxval,
		double *	yval,
		int	nyval )

Interpolates a 2-dimensional table with variable tablesize. Uses the srch function to bracket x or y between two xval's (or yval's), and then performs a linear interpolation on z. Out of bounds x and y values are truncated. This routine can handle NXVAL or NYVAL = 1. This function replicates BRAWLER v7.5 tbl2.f

Parameters

x	real - z(x,y) is the desired output
y	real - z(x,y) is the desired output
z	array dim(nxval,nyval) of (real) - lookup table
xval	array dim(nxval) of (real) - defines values of x for which z is tabulated. xval must be monotonically increasing
nxval	int - number of table points for first z-index
yval	array dim(nyval) of (real) - defines values of y for which z is tabulated. yval must be monotonically increasing
nyval	int - number of table points for second z-index

Returns: interpolated value of z(x,y), out-of-range x's truncated

◆ tbl2e()

double BRAWLER::tbl2e	(	double	x,
		double	y,
		double *	z,
		double *	xval,
		int	nxval,
		double *	yval,
		int	nyval )

Interpolates a 2-dimensional table with variable tablesize. This function replicates BRAWLER v7.5 tbl2e.f

Parameters

x	real - z(x,y) is the desired output
y	real - z(x,y) is the desired output
z	array dim(nxval,nyval) of (real) - lookup table
xval	array dim(nxval) of (real) - defines values of x for which z is tabulated. xval must be monotonically increasing
nxval	int - number of table points for first z-index
yval	array dim(nyval) of (real) - defines values of y for which z is tabulated. yval must be monotonically increasing
nyval	int - number of table points for second z-index

Returns: interpolated value of z(x,y), out-of-range x's extrapolated

◆ vsplit()

void BRAWLER::vsplit	(	const UtVec3d &	v,
		const UtVec3d &	x,
		UtVec3d &	vl,
		UtVec3d &	vt )

Splits a vector into parallel & perpendicular parts This function replicates BRAWLER v7.5 vsplit.f

Parameters

v	- vector to be split
x	- vector that defines "parallel" direction
vl	- part of "v" parallel to "x"
vt	- part of "v" transverse to "x"

◆ xlimit()

double BRAWLER::xlimit	(	const double	xreq,
		const double	xmax,
		const double	xmin )

Forces value to lie in a specified range This function replicates BRAWLER v7.5 xlimit.f

Parameters

xreq	real - value to be limited to range
xmax	real - upper range limit
xmin	real - lower range limit

Returns: xmin if xreq < xmin, xmax if xreq > xmax, xreq if xmin <= xreq <= xmax
