Class Strtri

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

public class Strtri
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 * ======= * * STRTRI computes the inverse of a real upper or lower triangular * matrix A. * * This is the Level 3 BLAS version of the algorithm. * * Arguments * ========= * * UPLO (input) CHARACTER*1 * = 'U': A is upper triangular; * = 'L': A is lower triangular. * * DIAG (input) CHARACTER*1 * = 'N': A is non-unit triangular; * = 'U': A is unit triangular. * * N (input) INTEGER * The order of the matrix A. N >= 0. * * A (input/output) REAL array, dimension (LDA,N) * On entry, the triangular matrix A. If UPLO = 'U', the * leading N-by-N upper triangular part of the array A contains * the upper triangular matrix, and the strictly lower * triangular part of A is not referenced. If UPLO = 'L', the * leading N-by-N lower triangular part of the array A contains * the lower triangular matrix, and the strictly upper * triangular part of A is not referenced. If DIAG = 'U', the * diagonal elements of A are also not referenced and are * assumed to be 1. * On exit, the (triangular) inverse of the original matrix, in * the same storage format. * * LDA (input) INTEGER * The leading dimension of the array A. LDA >= max(1,N). * * INFO (output) INTEGER * = 0: successful exit * < 0: if INFO = -i, the i-th argument had an illegal value * > 0: if INFO = i, A(i,i) is exactly zero. The triangular * matrix is singular and its inverse can not be computed. * * ===================================================================== * * .. Parameters ..
