Class SLARGV

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

public class SLARGV
extends java.lang.Object

SLARGV is a simplified interface to the JLAPACK routine slargv.
This interface converts Java-style 2D row-major arrays into
the 1D column-major linearized arrays expected by the lower
level JLAPACK routines.  Using this interface also allows you
to omit offset and leading dimension arguments.  However, because
of these conversions, these routines will be slower than the low
level ones.  Following is the description from the original Fortran
source.  Contact seymour@cs.utk.edu with any questions.

* .. * * Purpose * ======= * * SLARGV generates a vector of real plane rotations, determined by * elements of the real vectors x and y. For i = 1,2,...,n * * ( c(i) s(i) ) ( x(i) ) = ( a(i) ) * ( -s(i) c(i) ) ( y(i) ) = ( 0 ) * * Arguments * ========= * * N (input) INTEGER * The number of plane rotations to be generated. * * X (input/output) REAL array, * dimension (1+(N-1)*INCX) * On entry, the vector x. * On exit, x(i) is overwritten by a(i), for i = 1,...,n. * * INCX (input) INTEGER * The increment between elements of X. INCX > 0. * * Y (input/output) REAL array, * dimension (1+(N-1)*INCY) * On entry, the vector y. * On exit, the sines of the plane rotations. * * INCY (input) INTEGER * The increment between elements of Y. INCY > 0. * * C (output) REAL array, dimension (1+(N-1)*INCC) * The cosines of the plane rotations. * * INCC (input) INTEGER * The increment between elements of C. INCC > 0. * * ===================================================================== * * .. Parameters ..
