components

Int32 status

return status. A non-zero value indicates an error or a request for further information. See SCU_solve for details.

Int32 alloc_status

the return status from the last attempted internal workspace array allocation or deallocation. A non-zero value indicates that the allocation or deallocation was unsuccessful, and corresponds to the fortran STAT= value on the user’s system.

Int32 inertia[3]

the inertia of \(S\) when the extended matrix is symmetric. Specifically, inertia(i), i=0,1,2 give the number of positive, negative and zero eigenvalues of \(S\) respectively.
