Description
Local values of polynomial covariance coefficients.
Left-hand-side covariance matrix for system of intrinsic kriging
equations.
Right-hand-side covariance vector for system of intrinsic kriging
equations.
Dublicate of array Bkv.
Spatial coordinates and parameter values of input data. X-spacing between grid nodes.
Y-spacing between grid nodes.
Local value of estimation error variance. Local value of point estimate.
Condition flag: 0 = no bull's-eye; 1 = bull's-eye.
Condition flag: 0 = non-converging covariance solutions; 1 =
converging solutions.

fiinction. Dimensioned 15x4x3: up to 15 possible polynomial covariance forms depending on v; 4 coefficients in order as AO, CO, CI, and C2; 3 possible orders of intrinsity. An entry of 1
indicates a non-zero coefficient value for that covariance form
and the given v-value. Entries of 0 indicate the coefficient is not
used in that form.
