Range ()

The upper bound. Range (const double point)

Range (const double lo, const double hi)

Initializes to specified range. bool Contains (const double d) const

Determines if a point is contained within the range. bool Contains (const Range &r) const

Determines if another range overlaps with this one. double Hi () const

Get the upper bound. double & Hi ()

Modify the upper bound. double Lo () const

Get the lower bound. double & Lo ()

Modify the lower bound. double Mid () const

Gets the midpoint of this range. bool operator!= (const Range &rhs) const

Compare with another range for strict equality. Range operator& (const Range &rhs) const

Shrinks this range to be the overlap with another range; this makes an empty set if there is no overlap. Range & operator&= (const Range &rhs)

Shrinks this range to be the overlap with another range; this makes an empty set if there is no overlap. Range operator* (const double d) const

Scale the bounds by the given double. Range & operator*= (const double d)

Scale the bounds by the given double. bool operator< (const Range &rhs) const

Compare with another range. bool operator== (const Range &rhs) const

Compare with another range for strict equality. bool operator> (const Range &rhs) const

Compare with another range. Range operator| (const Range &rhs) const

Expands this range to include another range. Range & operator|= (const Range &rhs)

Expands this range to include another range. std::string ToString () const

Returns a string representation of an object. double Width () const

Gets the span of the range (hi - lo).

Range operator* (const double d, const Range &r)

Scale the bounds by the given double.

Simple real-valued range.

It contains an upper and lower bound.

Definition at line 31 of file range.hpp.

mlpack::math::Range::Range ()\fC [inline]\fP

The upper bound. Initialize to an empty set (where lo > hi).

mlpack::math::Range::Range (const doublepoint)\fC [inline]\fP

mlpack::math::Range::Range (const doublelo, const doublehi)\fC [inline]\fP

Initializes to specified range.

Parameters:

lo Lower bound of the range.

hi Upper bound of the range.

bool mlpack::math::Range::Contains (const doubled) const\fC [inline]\fP

Determines if a point is contained within the range.

Parameters:

d Point to check.

bool mlpack::math::Range::Contains (const \fBRange\fP &r) const\fC [inline]\fP

Determines if another range overlaps with this one.

Parameters:

r Other range.

Returns:

true if ranges overlap at all.

double mlpack::math::Range::Hi () const\fC [inline]\fP

Get the upper bound.

double& mlpack::math::Range::Hi ()\fC [inline]\fP

Modify the upper bound.

Definition at line 65 of file range.hpp.

References hi.

double mlpack::math::Range::Lo () const\fC [inline]\fP

Get the lower bound.

Definition at line 58 of file range.hpp.

References lo.

double& mlpack::math::Range::Lo ()\fC [inline]\fP

References lo.

double mlpack::math::Range::Mid () const\fC [inline]\fP

Gets the midpoint of this range.

bool mlpack::math::Range::operator!= (const \fBRange\fP &rhs) const\fC [inline]\fP

Compare with another range for strict equality.

Parameters:

rhs Other range.

\fBRange\fP mlpack::math::Range::operator& (const \fBRange\fP &rhs) const\fC [inline]\fP

Shrinks this range to be the overlap with another range; this makes an empty set if there is no overlap.

Parameters:

rhs Other range.

\fBRange\fP& mlpack::math::Range::operator&= (const \fBRange\fP &rhs)\fC [inline]\fP

Shrinks this range to be the overlap with another range; this makes an empty set if there is no overlap.

Parameters:

rhs Other range.

\fBRange\fP mlpack::math::Range::operator* (const doubled) const\fC [inline]\fP

Scale the bounds by the given double.

Parameters:

d Scaling factor.

\fBRange\fP& mlpack::math::Range::operator*= (const doubled)\fC [inline]\fP

Scale the bounds by the given double.

Parameters:

d Scaling factor.

bool mlpack::math::Range::operator< (const \fBRange\fP &rhs) const\fC [inline]\fP

Compare with another range. For Range objects x and y, x < y means that x is strictly less than y and does not overlap at all.

Parameters:

rhs Other range.

bool mlpack::math::Range::operator== (const \fBRange\fP &rhs) const\fC [inline]\fP

Compare with another range for strict equality.

Parameters:

rhs Other range.

bool mlpack::math::Range::operator> (const \fBRange\fP &rhs) const\fC [inline]\fP

Compare with another range. For Range objects x and y, x < y means that x is strictly less than y and does not overlap at all.

Parameters:

rhs Other range.

\fBRange\fP mlpack::math::Range::operator| (const \fBRange\fP &rhs) const\fC [inline]\fP

Expands this range to include another range.

Parameters:

rhs Range to include.

\fBRange\fP& mlpack::math::Range::operator|= (const \fBRange\fP &rhs)\fC [inline]\fP

Expands this range to include another range.

Parameters:

rhs Range to include.

std::string mlpack::math::Range::ToString () const\fC [inline]\fP

Returns a string representation of an object.
