Typedef Documentation

typedef double gridripper::GReal_t

Real number type.

It can be float, double or long double.

Function Documentation

void gridripper::copy	(	const tvalarray< IntArray > &	source,
		tvalarray< IntArray > &	dest
	)			[inline]

Copy (also realloc if necessary).

The instance for T==tvalarray<>.

GReal_t gridripper::normsquare

(

GReal_t

x

)

[inline]

Normsquare function.

GReal_t gridripper::normsquare

(

GComplex_t

x

)

[inline]

Normsquare function.

void gridripper::resize	(	tvalarray< IntArray > &	arr,
		unsigned	_n,
		IntArray	value = IntArray()
	)			[inline]

Resize hyper-array and initialize all elements.

This is a hack by Andras Laszlo to make it work for tvalarray< IntArray >.

GComplex_t gridripper::square

(

GComplex_t

x

)

[inline]

Square function.

GReal_t gridripper::square

(

GReal_t

x

)

[inline]

Square function.

Variable Documentation

const GReal_t gridripper::GNaN = NAN

Mathematical constants partly taken from cmath GNU long double extension.

const GReal_t gridripper::GReal_EPSILON

Initial value:

 sizeof(GReal_t) == 4? FLT_EPSILON :
                              sizeof(GReal_t) == 8? DBL_EPSILON :
                                                    LDBL_EPSILON

Smallest real number for which 1+epsilon != 1.
