CORE_slaed3_updatevectors -

Parameters
[in]opType of operation to apply = PlasmaLaed3Update1: Apply the GEMM on the first subproblem = PlasmaLaed3Update2: Apply the GEMM on the second subproblem and merge the eigenvalues. = PlasmaLaed3UpdateAll: Apply all operations in one call.
[in]wsmodeSpecifies the amount of extra workspace used for the computations. = 0 : means that no extra workspace is available (WORK = NULL). S = Q2 + n12 * n1 + n23 * (n-n1) is used as the workspace to sequentially apply the updates = 1 : means that extra workspace has been allocated in CORE_slaed3_computevectors() to apply the updates in parallel. If op = PlasmaLaed3Update1, the first subproblem is updated. If op = PlasmaLaed3Update2, the second subproblem is updated. = 3 : means that extra workspace has been allocated in after K has been computed in CORE_slaed2_computeK(). Allows to apply both updates in parallel as previously.
[in]nn specifies the dimension of the symmetric tridiagonal matrix
[in]n1n1 specifies the location of the last eigenvalue of the first subproblem min(1, n) <= n1 <= n/2
[in]KK specifies the number of non-deflated eigenvalues
[in]il_nondefThe first eigenvector index when computing only a subset of all eigenpairs
[in]iu_nondefThe last eigenvector index when computing only a subset of all eigenpairs
[out]QThe current eigenvectors
[in]ldqLDQ specifies the leading direction of Q
[in,out]Q2The updated eigenvectors
[in]ctotctot indicates the number of vectors of each type in the Q matrix. 0- non-zero in the upper half only 1- dense 2- non-zero in the lower half only 3- deflated
[in]WW is the place were will be stored the updated eigenvectors
[in]startstart specifies the first column index to be considered by this kernel
[in]endend specifies the last column index to be considered by this kernel
