SofaRy Method

Applies a rotation about the Y-axis by the specified angle and returns the corresponding rotation matrix.

Definition

Namespace: ASCOM.Tools
Assembly: ASCOM.AstrometryTools (in ASCOM.AstrometryTools.dll) Version: 3.0.0-rc.1+86c25ce733aebb4d8b1b8a62e84770ea5e972bea

C#

public static void Ry(
	double theta,
	double[] r
)

VB

Public Shared Sub Ry ( 
	theta As Double,
	r As Double()
)

Parameters

theta Double: The angle of rotation in radians. Positive values represent a right-handed rotation about the Y-axis.
r Double: An array of nine elements that receives the resulting 3×3 rotation matrix in row-major order. The array must not be null and must have a length of at least 9.

Remarks

This method is a P/Invoke wrapper for the SOFA library function 'iauRy'. The resulting matrix can be used to transform 3D vectors by applying a rotation about the Y-axis. The input array is overwritten with the computed matrix values.

Exceptions

ArgumentNullException	Thrown if any array parameter is null.
ArgumentException	Thrown if any array parameter has incorrect length.
