Read the benchmark definitions in src/benchmarks/micro/libraries/System.Numerics.Vectors/Perf_Matrix3x2.cs at lines 27-28 and 48-49. Run the provided benchmarks_ci.py command with the System.Numerics.Tests.Perf_Matrix3x2 filter, then compare the reported AOT/WebAssembly results with the linked report. Done should identify whether the measured improvements require follow-up.
