annotate libinterp/dldfcn/__eigs__.cc @ 25696:3b6691ff0f59

Fix eigs for generalized problems with user defined function (bug #54167). * eigs-base.cc (EigsRealSymmetricFunc, EigsRealNonSymmetricFunc, EigsComplexNonSymmetricFunc): Add B as input argument and manage mode = 1 and mode = 3. * eigs-base.h: Declare EigsRealSymmetricFunc, EigsRealNonSymmetricFunc, and EigsComplexNonSymmetricFunc template functions. * __eigs__.cc: Call EigsRealSymmetricFunc, EigsRealNonSymmetricFunc, and EigsComplexNonSymmetricFunc with the new input argument B. * scripts/sparse/eigs.m: Add BIST tests.
