a | an object of a type that models Kriging Constraint | |
M | an object of type Symmetric Matrix (see the description of kriging in 2.4.1 for a detailed description of this type) | |
V | an object of type Vector (see the description of kriging in 2.4.1 for a detailed description of this type) | |
first,last | Two Input Iterators to a range of types that model Neighborhood | |
u | an object of type that models Location |
a(M,V,u,first,last)
Return type: | a type convertible to unsigned int | |
Semantics: | The total size N of the kriging system is computed from the total number of neighboring data. The kriging matrix M is then resized to N*N, and vector V (second member of the kriging system) is resized to N. Finally, the part of the system that does not depend on the covariances is computed, possibly using location u and the neighboring geo-values of u. The returned value is the total number of conditioning data, i.e. the sum of the sizes of the all neighborhoods. |
