Class Slarfx

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

public class Slarfx
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.
Contact seymour@cs.utk.edu with any questions.

* .. * * Purpose * ======= * * SLARFX applies a real elementary reflector H to a real m by n * matrix C, from either the left or the right. H is represented in the * form * * H = I - tau * v * v' * * where tau is a real scalar and v is a real vector. * * If tau = 0, then H is taken to be the unit matrix * * This version uses inline code if H has order < 11. * * Arguments * ========= * * SIDE (input) CHARACTER*1 * = 'L': form H * C * = 'R': form C * H * * M (input) INTEGER * The number of rows of the matrix C. * * N (input) INTEGER * The number of columns of the matrix C. * * V (input) REAL array, dimension (M) if SIDE = 'L' * or (N) if SIDE = 'R' * The vector v in the representation of H. * * TAU (input) REAL * The value tau in the representation of H. * * C (input/output) REAL array, dimension (LDC,N) * On entry, the m by n matrix C. * On exit, C is overwritten by the matrix H * C if SIDE = 'L', * or C * H if SIDE = 'R'. * * LDC (input) INTEGER * The leading dimension of the array C. LDA >= (1,M). * * WORK (workspace) REAL array, dimension * (N) if SIDE = 'L' * or (M) if SIDE = 'R' * WORK is not referenced if H has order < 11. * * ===================================================================== * * ..
