ARGUMENTS TRANSA(input) TRANSA specifies the form of op( A ) to be used in the matrix multiplication as follows: 0 : operate with matrix 1 : operate with transpose matrix 2 : operate with the conjugate transpose of matrix. 2 is equivalent to 1 if matrix is real. Unchanged on exit. M(input) On entry, M specifies the number of rows in the matrix A. Unchanged on exit. N(input) On entry, N specifies the number of columns in the matrix C. Unchanged on exit. K(input) On entry, K specifies the number of columns in the matrix A. Unchanged on exit. ALPHA(input) On entry, ALPHA specifies the scalar alpha. Unchanged on exit. DESCRA (input) Descriptor argument. Five element integer array: DESCRA(1) matrix structure 0 : general 1 : symmetric (A=A') 2 : Hermitian (A= CONJG(A')) 3 : Triangular 4 : Skew(Anti)-Symmetric (A=-A') 5 : Diagonal 6 : Skew-Hermitian (A= -CONJG(A')) DESCRA(2) upper/lower triangular indicator 1 : lower 2 : upper DESCRA(3) main diagonal type 0 : non-unit 1 : unit DESCRA(4) Array base (NOT IMPLEMENTED) 0 : C/C++ compatible 1 : Fortran compatible DESCRA(5) repeated indices? (NOT IMPLEMENTED) 0 : unknown 1 : no repeated indices VAL(input) On entry, VAL is a scalar array of length NNZ=PNTR(MAXNZ+1)-PNTR(1)+1 consisting of entries of A. VAL can be viewed as a column major ordering of a row permutation of the Ellpack representation of A, where the Ellpack representation is permuted so that the rows are non-increasing in the number of nonzero entries. Values added for padding in Ellpack are not included in the Jagged-Diagonal format. Unchanged on exit. INDX(input) On entry, INDX is an integer array of length NNZ=PNTR(MAXNZ+1)-PNTR(1)+1 consisting of the column indices of the corresponding entries in VAL. Unchanged on exit. PNTR(input) On entry, PNTR is an integer array of length MAXNZ+1, where PNTR(I)-PNTR(1)+1 points to the location in VAL of the first element in the row-permuted Ellpack represenation of A. Unchanged on exit. MAXNZ(input) On entry, MAXNZ specifies the max number of nonzeros elements per row. Unchanged on exit. IPERM(input) On entry, IPERM is an integer array of length M such that I = IPERM(I'), where row I in the original Ellpack representation corresponds to row I' in the permuted representation. If IPERM(1) = 0, it is assumed by convention that IPERM(I) = I. IPERM is used to determine the order in which rows of C are updated. Unchanged on exit. B (input) Array of DIMENSION ( LDB, N ). Before entry with TRANSA = 0, the leading k by n part of the array B must contain the matrix B, otherwise the leading m by n part of the array B must contain the matrix B. Unchanged on exit. LDB (input) On entry, LDB specifies the first dimension of B as declared in the calling (sub) program. Unchanged on exit. BETA (input) On entry, BETA specifies the scalar beta. Unchanged on exit. C(input/output) Array of DIMENSION ( LDC, N ). Before entry with TRANSA = 0, the leading m by n part of the array C must contain the matrix C, otherwise the leading k by n part of the array C must contain the matrix C. On exit, the array C is overwritten by the matrix ( alpha*op( A )* B + beta*C ). LDC (input) On entry, LDC specifies the first dimension of C as declared in the calling (sub) program. Unchanged on exit.
