RawCoordinateSequence(Memory<Double>[], (Int32 RawDataIndex, Int32 DimensionIndex)[], Int32)

Initializes a new instance of the RawCoordinateSequence class.

Declaration
public RawCoordinateSequence(Memory<double>[] rawData, (int RawDataIndex, int DimensionIndex)[] dimensionMap, int measures)
Parameters
Type Name Description
Memory<Double>[] rawData

Contains the raw data for this sequence.
(T1, T2)<Int32, Int32>[] dimensionMap

Contains a pair of indexes to tell us, for each dimension, where to find its data in rawData.
Int32 measures

The value for Measures.

GetRawCoordinatesAndStride(Int32)

Gets the underlying Memory<T> for the ordinates at the given index, along with a "stride" value that represents how many slots there are between elements.

Declaration
public (Memory<double> Array, int Stride) GetRawCoordinatesAndStride(int ordinateIndex)
Parameters
Type Name Description
Int32 ordinateIndex

The index of the ordinate whose values to get, from TryGetOrdinateIndex(Ordinate, out Int32).
Returns
Type Description
(T1, T2)<Memory<Double>, Int32>

The underlying Memory<T> and stride.
Remarks

Assuming Count is nonzero, the first element of the returned array holds the first coordinate's value for the requested ordinate, and the last element of the returned array holds the last coordinate's value for the requested ordinate.
