Function Documentation

double correlationCoeff	(	QdRMatrixSeq_var	X_in,
		QdRMatrixSeq_var	Y_in,
		int	n
	)

calculates the correlation coefficient between two 3 element vectors

Returns:

a double with correlation coefficient

Parameters:

	X_in	- 3 component vector with time series 1
	Y_in	- 3 component vector with time series 2
	n	- number of elements in the two vectors

QdRMatrix_var Q_MVAB_calc	(	QdRMatrixSeq_var	B,
		QdRMatrixSeq_var	V,
		QdRMatrix_var	U,
		QdRMatrixSeq_var	Valf,
		QdRScalarSeq_var	N,
		double *	wl,
		double *	cc,
		int	nestsize,
		bool	doHT
	)

Calculates the covariance matrix of the magnetic field.

Parameters:

	B	- vector time series with the magnetic field in units of nT
	V	- vector time series with plasma velocity in units of km/s
	U	- holds the calculated velocity on successful return
	nestsize	- number of elements in B and V.
	full	- 0 to do MVAB only, 1 to include HT analysis

double slope	(	QdRMatrixSeq_var	X_in,
		QdRMatrixSeq_var	Y_in,
		int	n
	)

calculates the regression line

Returns:

a double with the slope, i.e., the coeff b in y(x) = a + bx

Parameters:

	X_in	- 3 component vector with time series 1
	Y_in	- 3 component vector with time series 2
	n	- number of elements in the two vectors

QdRMatrix_var V_HofTel	(	QdRMatrixSeq_var	B,
		QdRMatrixSeq_var	V,
		int	nestsize
	)

Returns the DeHoffmann-Teller velocity for the given magnetic field and plasma velocity. The electric field used in the calculation is taken from the proxy E = - V x B.

Parameters:

	B	- vector time series with the magnetic field in units of nT
	V	- vector time series with plasma velocity in units of km/s
	nestsize	- number of elements in B and V.
