verify_bem_fresnel

Verify BEM vs Fresnel dyadic Green’s functions via least-squares scaling.

Reads the CSV produced by compare_BEM_dyadic.py, fits a complex scalar s_ij for each tensor component such that ||s_ij * G_BEM - G_Fresnel||^2 is minimised, then reports the per-component and averaged scale factors along with the relative RMS error after scaling.

To use this script: python -m mqed.BEM.verify_bem_fresnel path/to/bem_vs_fresnel.csv

mqed.BEM.verify_bem_fresnel.fit_scale(re_bem, im_bem, re_fresnel, im_fresnel)

Fit complex scalar s minimising ||s * G_BEM - G_Fresnel||^2.

mqed.BEM.verify_bem_fresnel.relative_rms(s, re_bem, im_bem, re_fresnel, im_fresnel)

Relative RMS error after applying scale factor s.
