Typedef Documentation

using cm_vec = std::vector<std::complex<double>>

A template matrix class for quantum (q) operators and general linear algebra.

qmatrix is a row-major matrix container for NRG quantum calculations, supporting:

• Generic template types (double, std::complex<double>)

• Dense matrix operations and eigenvalue decomposition

• Kronecker products for tensor operations

• Intel MKL optimized BLAS/LAPACK routines

The matrix is stored in flat STL vector in row-major order (LAPACK_ROW_MAJOR), with element (i,j) at index i*column+j.

Note

All indexing is 0-based. OpenMP parallelization used for large operations.

Template Parameters:

T – Matrix element type (default: double). Supports std::complex<double>.
