java.lang.Object | +----org.netlib.lapack.Dlar2v
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 * ======= * * 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 ..
