Parameters

Y

Type: ILNumericsInArraycomplex
Data values, matrix with measured values at the n data points specified by X. Size [k x n].

X

Type: ILNumericsInArrayDouble
Data points, matrix with sample locations of dimension m in n columns. At least 2 samples must be provided.

variogram (Optional)

Type: SystemFuncInArrayDouble, RetArrayDouble
[Optional] Variogram function of the euclidian distances. Default: PowerLawVariogram(InArrayDouble)

errors (Optional)

Type: ILNumericsInArrayDouble
[Optional] (this paramter is currently ignored)

doChecks (Optional)

Type: SystemBoolean
[Optional] True: check the distances between points provided in X for too small values (default). False: do not perform these checks (and save some computations).

alpha (Optional)

Type: SystemNullableDouble
[Optional] Default alpha factor for the default Power variogramm. Ignored, if a custom variogramm was specified. Default: auto computed.

beta (Optional)

Type: SystemNullableDouble
[Optional] Default beta exponent for the default Power variogramm. Ignored, if a custom variogramm was specified. Range: [0 ...). Default: 1.5.

The optional parameter doChecks is used to prevent the kriging interpolator from instability effects caused by disadvantageous positions X. If points in X are too close to each other, the resulting distance matrix (and its inversion later on) might cause singularity problems. Therefore and if doChecks is true checks are automatically made for that and potential redundant values are removed from the data set.
