5.3.2 VS2INT/VS2DIN/VS2OUT

1.

Function

Continuously reads and calculates the mean and dispersion of two types of vector data. VS2INT initializes. VS2DIN reads out data. VS2OUT calculates the statistics.

2.

Call

CALL VS2INT(WZ,NW,IX,IY)
CALL VS2DIN(WZ,NW,IX,IY,X,Y)
CALL VS2OUT(WZ,NW,IX,IY)

3.

Explanation of Parameters

WZ	(R)	A 3-D array of size (IX,IY,5). It is used as the working area while VS2DIN is called. When VS2OUT is called,
		the mean of X is returned in WZ(i, j,1),
		the mean of Y in WZ(i, j,2),
		the dispersion of X in WZ(i, j,3),
		the dispersion of Y in WZ(i, j,4),
		the covariance of X and Y in WZ(i, j,5)
NW	(I)	A 2-D array of size (IX, IY).  It stores the number of vector data that has been processed.
IX	(I)	The size of the first dimension of WZ, the size of the first dimension of NW, and length of X.
IY	(I)	The size of the second dimension of WZ, the size of the second dimension of NW, and length of Y.
X	(R)	The length of the vector data to read. An array of length IX
Y	(R)	The length of the vector data to read. An array of length IY.
