rotates the two seismograms to the great circle path transverse (X) and radial (Y). It is assumed that the two seismograms orientation are perpendicular to each other and are oriented in the east, x and north, y, directions. They must also have the same number of data points.

rotates the two seismograms by the given angle. It is assumed that the two seismograms orientation are perpendicular to each other and that the sense of the rotation is from x towards y.

Throws:

IncompatibleSeismograms

edu.iris.Fissures.FissuresException

rotate

public static void rotate(float[] x,

                          double radians)
                   throws IncompatibleSeismograms

Rotates the x and y arrays by the given angle in radians. The x and y axis are assumed to be perpendicular. Theta, in radians, is positive from x towards y, and so a rotation of PI/2 puts x into y and -y into x.

Throws:

IncompatibleSeismograms

rotate

public static void rotate(float[] x,

Performs the rotation from the given matrix. It is assumed to be a pure rotation matrix (no translation) and the translation components of the affine transform are ignored if present.

Throws:
