Detailed Description

Expand per-station metrics from a reduced model back to the original station set.

Templated port of matlab/src/api/pfqn/pfqn_expand.m. The inverse of pfqn_unique: row i of each output is row mapping(i) of the corresponding input, so every station of a replicated group receives the metrics computed once for its representative.

Arithmetic: EXACT-CAPABLE. The routine copies values and performs no arithmetic at all, so it is exact in every arithmetic by construction and carries no transcendental gate.
