Class Dsptrs

java.lang.Object
  extended by org.netlib.lapack.Dsptrs

public class Dsptrs
extends java.lang.Object

Following is the description from the original
Fortran source.  For each array argument, the Java
version will include an integer offset parameter, so
the arguments may not match the description exactly.

* .. * * Purpose * ======= * * DSPTRS solves a system of linear equations A*X = B with a real * symmetric matrix A stored in packed format using the factorization * A = U*D*U**T or A = L*D*L**T computed by DSPTRF. * * Arguments * ========= * * UPLO (input) CHARACTER*1 * Specifies whether the details of the factorization are stored * as an upper or lower triangular matrix. * = 'U': Upper triangular, form is A = U*D*U**T; * = 'L': Lower triangular, form is A = L*D*L**T. * * N (input) INTEGER * The order of the matrix A. N >= 0. * * NRHS (input) INTEGER * The number of right hand sides, i.e., the number of columns * of the matrix B. NRHS >= 0. * * AP (input) DOUBLE PRECISION array, dimension (N*(N+1)/2) * The block diagonal matrix D and the multipliers used to * obtain the factor U or L as computed by DSPTRF, stored as a * packed triangular matrix. * * IPIV (input) INTEGER array, dimension (N) * Details of the interchanges and the block structure of D * as determined by DSPTRF. * * B (input/output) DOUBLE PRECISION array, dimension (LDB,NRHS) * On entry, the right hand side matrix B. * On exit, the solution matrix X. * * LDB (input) INTEGER * The leading dimension of the array B. LDB >= max(1,N). * * INFO (output) INTEGER * = 0: successful exit * < 0: if INFO = -i, the i-th argument had an illegal value * * ===================================================================== * * ..
