Class Slar2v

java.lang.Object
  extended by org.netlib.lapack.Slar2v

public class Slar2v
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 * ======= * * SLAR2V 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) REAL array, * dimension (1+(N-1)*INCX) * The vector x. * * Y (input/output) REAL array, * dimension (1+(N-1)*INCX) * The vector y. * * Z (input/output) REAL 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) REAL array, dimension (1+(N-1)*INCC) * The cosines of the plane rotations. * * S (input) REAL 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 ..
