SUMXMY2 function

Returns the sum of squares of differences of corresponding values in two arrays.

Syntax

SUMXMY2(array_x,array_y)

Array_x     is the first array or range of values.

Array_y     is the second array or range of values.

Remarks

  • The arguments should be either numbers or names, arrays, or references that contain numbers.
