| Declaration |
Explanation & Details |
| TNameStrType = string[50]; |
Defines string type used for column headers. |
| TNormType = (ntColwise, ntRowwise, ntSpectral, ntFrobenius); |
The type declaration TNormType declares the various types of matrix norms supported by TMatrix:
| ntColwise |
largest column sum (the "1-norm") |
| ntRowwise |
largest row sum (the "infinity norm") |
| ntSpectral |
the largest singular value of the matrix |
| ntFrobenius |
the Frobenius norm (also known as Euclidean norm) |
|
| TNotifyEvent = procedure (Sender: TObject); |
Indicates the occurrence of an event.
|
| TOnCalcDistanceEvent = procedure (Sender: TObject; Row1, Row2: integer; var Distance: double) of object; |
Declares the event type triggered when calculating distances in multivariate spaces. |
| TOnPercentDoneEvent = procedure (Sender: TObject; PercentDone: integer; |
Is used to indicate the progress of a time-consuming process. The parameter PercentDone contains a number between 0 and 100 which corresponds to the state of the process. |
| TSortExchgEvent = procedure (Sender: TObject; ExchgWhat: byte; index1, index2, first, last: longint); |
Event triggered by the sorting process |
| TOrientation = (orVert, orHoriz); |
Defines the two orientations or axes (vertical and horizontal). |
| TPeakParamsList = array of TGaussPeakParams; |
Declares the list of peak parameters used by the function CreateGaussianPeaks. |
TPoint = record
X: integer;
Y: integer;
end; |
A point defined by integer coordinates |
| TPDblArray = array of TPointDouble; |
Array of points (used for polygons in the world coordinate system) |
| TPlotMode = (pmSurface, pmIsoLines, pmSurfIso); |
Defines the style of the graphics used to create artificial contour plots (currently not used in DataLab, just declared for compatibility reasons). |
TPointDouble = record
X: double;
Y: double;
end; |
Declares a point using double coordinates. |
TPreDefColPals = (cpRainbow, cpBW,cpCycRainbow,
cpGeo, cpHighContrast, cpBipolar, cpFringes, cpBWThreshold,
cpClassColors, cpMorgenStemning); |
Defines the predefined color palettes. |
TRect = record
Left: Integer;
Top: Integer;
Right: Integer;
Bottom: Integer;
end;
|
Defines the edges of a rectangle. |
TRegModel = (rmNone, rmLinear, rmParabolic,
rmGaussian, rmReciLin, rmHyperbolic,
rmReciHyperbolic, rmLog, rmReciLog, rmPower,
rmExpo, rmHoerl, rmCircle,
rmPolynomial, rmCenteredPoly); |
Defines the various regression models which are supported by TCurveFit. |
TRegRootKey = (hkeyClassesRoot, hkeyCurrentUser,
hkeyLocalMachine, hkeyUsers, hkeyPerformanceData,
hkeyCurrentConfig, hkeyDynData); |
Defines the root keys for accessing the Windows registry. |
TRescaleMode = (sctMeanCenter, sctStandardize,
sctConstSum, sctConstSquaredSum, sctMaxAbs,
sctRange, sctQNormalize, sctSquash, sctUndefined); |
Defines the available scaling mode (see RescaleVector and RescaleMatrix for more). |
TRFReport = record
RelClsError : Double;
AvgCE : Double;
RMSError : Double;
AvgError : Double;
AvgRelError : Double;
OOBRelClsError : Double;
OOBAvgCE : Double;
OOBRMSError : Double;
OOBAvgError : Double;
