Class Spotrs

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

public class Spotrs
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 * ======= * * SPOTRS solves a system of linear equations A*X = B with a symmetric * positive definite matrix A using the Cholesky factorization * A = U**T*U or A = L*L**T computed by SPOTRF. * * Arguments * ========= * * UPLO (input) CHARACTER*1 * = 'U': Upper triangle of A is stored; * = 'L': Lower triangle of A is stored. * * 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. * * A (input) REAL array, dimension (LDA,N) * The triangular factor U or L from the Cholesky factorization * A = U**T*U or A = L*L**T, as computed by SPOTRF. * * LDA (input) INTEGER * The leading dimension of the array A. LDA >= max(1,N). * * B (input/output) REAL 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 * * ===================================================================== * * ..
