Sample Variance PtByPt (Not in Base Package)

Computes the mean and sample variance of the values in the set of input data. Details

initialize, when TRUE, initializes the internal state of the VI.
input data is a set of input data.
sample length is the length of each set of incoming data. The VI performs computation for each set of data. The default is 100. When you set sample length to zero, the VI calculates a cumulative solution for the input data from the time that you called or initialized the VI. When the sample length setting is greater than zero, the VI calculates the solution for only the newest set of input data.
mean is the mean of the input point values.
sample variance is the sample variance of the set of input point values.
error returns any error or warning condition from the VI. Refer to Point By Point Error Codes for more information about these conditions.

Note  To compute the sample standard deviation of X, take the square root of sample variance.
