The function also returns the number of data points, the mean and the sum. This example function creates a series of data, calls the function, then reports the results.
Comments: Comment added by Bernhard Schaffer: To calcualte the standard deviation of an image (any size) you can also use the DM command variance() and then take the square-root of the result: image IMG number IMGsdev = SQRT(variance(IMG
