+----com.ibm.math.array.GivensRotation
- public final class GivensRotation
- extends Object
GivensRotation = represents a Givens plane rotation.
This class is used to encapsulate the four parameters
describing a Givens plane rotation, as returned from
the BLAS drotg operation.
-
cos
- The cosine of the Givens rotation angle
-
r
- The r parameter of the Givens rotation
-
sin
- The sine of the Givens rotation angle
-
z
- The z parameter of the Givens rotation
-
GivensRotation(double, double, double, double)
