Class ROTG

java.lang.Object

org.ojalgo.array.blas.ROTG

All Implemented Interfaces:

BLAS1

public abstract class ROTG
extends Object
implements BLAS1

Given the Cartesian coordinates (a, b) of a point, these routines return the parameters c, s, r, and z associated with the Givens rotation. The parameters c and s define a unitary matrix such that: Equation The parameter z is defined such that if |a| > |b|, z is s; otherwise if c is not 0 z is 1/c; otherwise z is 1.
