IMeasure* Sleipnir::CMeasureInnerProduct::Clone ( ) const [inline, virtual]

Create a copy of the current measure object.

Returns:
Copy of the current measure object.
Remarks:
Caller is, of course, responsible for destroying the created object.

Implements Sleipnir::IMeasure.

Definition at line 635 of file measure.h.

const char* Sleipnir::CMeasureInnerProduct::GetName ( ) const [inline, virtual]

Return the human-readable unique identifier of the measure type.

Returns:
The string identifier of the measure type.

Implements Sleipnir::IMeasure.

Definition at line 627 of file measure.h.

bool Sleipnir::CMeasureInnerProduct::IsRank ( ) const [inline, virtual]

Return true if the measure requires rank-based integer inputs.

Returns:
True if the measure requires rank-based input vectors.
Remarks:
The input vectors for rank measures should contain only floating point values with no fractional part; behavior is undefined if they don't.

Implements Sleipnir::IMeasure.

double Sleipnir::CMeasureInnerProduct::Measure ( const float *  adX,
size_t  iN,
const float *  adY,
size_t  iM,
EMap  eMap = EMapNone,
const float *  adWX = NULL,
const float *  adWY = NULL 
) const [virtual]

Calculate the measure between two given vectors with optional element weights.

Parameters:
adXFirst array of values.
iNLength of first array.
adYSecond array of values.
iMLength of second array.
eMapWay in which returned value should be centered (implementation-specific).
adWXIf non-null, weights of elements in the first array.
adWYIf non-null, weights of elements in the second array.
Returns:
Measure calculated between the two input vectors and, optionally, weights.
Remarks:
Pretty much every implementation will puke if given bad input; bounds checking etc. is minimal.
