Remarks This method symbolically factors the instance of the constructed matrix A, where A is
of type ComplexSparseMatrix and is Hermitian positive definite. The factorization is obtained in several steps:
- First, matrix
A is permuted to reduce fill-in, leading to a sparse Hermitian positive definite
matrix .
- Then, matrix is
symbolically factored.
