double doublevector_correlation	(	DOUBLEVECTOR *	,
		DOUBLEVECTOR *	,
		double	,
		double	,
		long	,
		double
	)

Name: doublevector_correlation, floatvector_correlation, longvector_correlation

Synopsis: double doublevector_correlation(DOUBLEVECTOR *,DOUBLEVECTOR *,double ,double ,long ,double ); float floatvector_correlation(FLOATVECTOR *,FLOATVECTOR *u,float ,float ,long ,float ); float longvector_correlation(LONGVECTOR *,LONGVECTOR *,float,float ,long ,long);

Description: It calculates the biased corretion between two vectors of the specified type.

Inputs: 1) the first vector; 2) the second vector; 3) the first vector mean; 4) the second vector mean; 5) the lag at which the correlation is calculated; 6) the value that identify "NO DATA"

Return: biased correlation (the division factor is the length of the vector minus the number of missing data)

		float	,
		float
	)

Name:floatmatrix_restricted _n_moment

Synopsis: float floatmatrix_n_moment(FLOATMATRIX *first,FLOATMATRIX *second, float ,float , float,float );

Description: It calculates the biased n moment of a vector or a matrix of the specified type as floatmatrix_n_moment but it uses the subset of points that are not novalue2 in a second nmatrix

Inputs: 1) the first matrix; 2) The second matrix; 3) the first matrix mean; 4) the second matrix mean; 5) the value that identify "NO DATA" or "MISSING DATA" in the first matrix (a sequence of mesasured data usually contains points where the data were not detected or monitored); 6) the vector that identify "NO DATA" in the second matrix

Return: biased n moment (the division factor is the length of the vector minus the number of missing data)
