TESTING/MATGEN/dlakf2.f(3) Library Functions Manual NAME TESTING/MATGEN/dlakf2.f SYNOPSIS Functions/Subroutines subroutine dlakf2 (m, n, a, lda, b, d, e, z, ldz) DLAKF2 Function/Subroutine Documentation subroutine dlakf2 (integer m, integer n, double precision, dimension( lda, * ) a, integer lda, double precision, dimension( lda, * ) b, double precision, dimension( lda, * ) d, double precision, dimension( lda, * ) e, double precision, dimension( ldz, * ) z, integer ldz) DLAKF2 Purpose: Form the 2*M*N by 2*M*N matrix Z = [ kron(In, A) -kron(B', Im) ] [ kron(In, D) -kron(E', Im) ], where In is the identity matrix of size n and X' is the transpose of X. kron(X, Y) is the Kronecker product between the matrices X and Y. Parameters M M is INTEGER Size of matrix, must be >= 1. N N is INTEGER Size of matrix, must be >= 1. A A is DOUBLE PRECISION, dimension ( LDA, M ) The matrix A in the output matrix Z. LDA LDA is INTEGER The leading dimension of A, B, D, and E. ( LDA >= M+N ) B B is DOUBLE PRECISION, dimension ( LDA, N ) D D is DOUBLE PRECISION, dimension ( LDA, M ) E E is DOUBLE PRECISION, dimension ( LDA, N ) The matrices used in forming the output matrix Z. Z Z is DOUBLE PRECISION, dimension ( LDZ, 2*M*N ) The resultant Kronecker M*N*2 by M*N*2 matrix (see above.) LDZ LDZ is INTEGER The leading dimension of Z. ( LDZ >= 2*M*N ) Author Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd. Definition at line 104 of file dlakf2.f.
