All Implemented Interfaces:
ArrayOperation

public abstract class ROTG extends Object implements ArrayOperation
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.
