// Description:
36
// Computes the weighted sum of a collection of slices from a source
37
// array, and stores the results in a slice of a target array. Note that
38
// the number of source slices and weights must match, and the extents of
39
// each source slice must match the extents of the target slice.
40
//
41
// Note: The implementation assumes that operator*(T, double) is defined,
42
// and that there is an implicit conversion from its result back to T.
43
//
44
// If you need to interpolate arrays of T other than double, you will
45
// likely want to create your own specialization of this function.
46
//
47
// The implementation should produce correct results for dense and sparse
48
// arrays, but may perform poorly on sparse.
