One query's scores against every choice, without copying.

public ReadOnlySpan<double> Row(int row)

Parameters — row is the query's index.

Returns — a window onto that row of the matrix, Columns values wide; empty when there were no choices.

Exceptions — ArgumentOutOfRangeException when row is outside the matrix.

Example — the second query's scores.

using Lodestar.Fuzzy;

string[] queries = ["new york", "boston"];
string[] choices = ["new york mets", "boston red sox", "atlanta braves"];

ReadOnlySpan<double> boston = Process.Cdist(queries, choices).Row(1);

int width = boston.Length;                       // => 3
double best = Math.Round(boston[1], 4);          // => 60

Remarks — a window, not a copy. The storage is row-major, so a row is contiguous and this hands back a span over it; ToArray is what copies. A row of a matrix with no columns is an empty span rather than a refusal, which is the shape the reference answers an empty choice list with.

Applies to — net10.0, netstandard2.0.
