Class Dlar2v

java.lang.Object
  extended by org.netlib.lapack.Dlar2v

public class Dlar2v
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 * ======= * * DLAR2V applies a vector of real plane rotations from both sides to * a sequence of 2-by-2 real symmetric matrices, defined by the elements * of the vectors x, y and z. For i = 1,2,...,n * * ( x(i) z(i) ) := ( c(i) s(i) ) ( x(i) z(i) ) ( c(i) -s(i) ) * ( z(i) y(i) ) ( -s(i) c(i) ) ( z(i) y(i) ) ( s(i) c(i) ) * * Arguments * ========= * * N (input) INTEGER * The number of plane rotations to be applied. * * X (input/output) DOUBLE PRECISION array, * dimension (1+(N-1)*INCX) * The vector x. * * Y (input/output) DOUBLE PRECISION array, * dimension (1+(N-1)*INCX) * The vector y. * * Z (input/output) DOUBLE PRECISION array, * dimension (1+(N-1)*INCX) * The vector z. * * INCX (input) INTEGER * The increment between elements of X, Y and Z. INCX > 0. * * C (input) DOUBLE PRECISION array, dimension (1+(N-1)*INCC) * The cosines of the plane rotations. * * S (input) DOUBLE PRECISION array, dimension (1+(N-1)*INCC) * The sines of the plane rotations. * * INCC (input) INTEGER * The increment between elements of C and S. INCC > 0. * * ===================================================================== * * .. Local Scalars ..
