Generate all excitations for a given determinant in the ilut Format
Get an element of a lMat. This replaces the old lMatAccess function pointer
Return the GAS spaces, where one particle can be created.
Return true, if an excitation exc from determinant det_I and a given pgen_diagnostic (sum 1/pgen) is considered to be problematic.
Read operation on a single block of data read from an hdf5 file
Read a lMat from a file
Set an element of a lMat
Write a string representation of this GAS specification to iunit
