LOBPCG method descriptor.
Description
LOBPCG method descriptor.
Usage
lobpcg(maxit = 200L, preconditioner = NULL, constraints = NULL)
Arguments
maxit
Maximum LOBPCG iterations.
preconditioner
Optional function taking a residual block and
returning a preconditioned block with the same dimensions.
constraints
Optional matrix whose columns span a subspace to deflate.
Iterates are kept orthogonal to this subspace in the Euclidean or
generalized B inner product. Native constrained LOBPCG is not promoted
yet; constrained problems use the honest reference path.
Value
An eigencore_method descriptor selecting LOBPCG. Built-in
standard Hermitian dense/CSC operators may use a native prototype;
unsupported cases route to the reference prototype.
