ARGUMENTS UPLO (input) Specifies whether the details of the factorization are stored as an upper or lower triangular matrix. = 'U': Upper trian- gular, form is A = U*D*U**H; = 'L': Lower triangular, form is A = L*D*L**H. N (input) The order of the matrix A. N >= 0. NRHS (input) The number of right hand sides, i.e., the number of columns of the matrix B. NRHS >= 0. A (input) The block diagonal matrix D and the multipliers used to obtain the factor U or L as computed by ZHETRF. LDA (input) The leading dimension of the array A. LDA >= max(1,N). IPIVOT (input) Details of the interchanges and the block structure of D as determined by ZHETRF. B (input/output) On entry, the right hand side matrix B. On exit, the solu- tion matrix X. LDB (input) The leading dimension of the array B. LDB >= max(1,N). INFO (output) = 0: successful exit < 0: if INFO = -i, the i-th argument had an illegal value 7 Nov 2015 zhetrs(3P)
