Description
Returns the Euclidean 'L-2' norm.
Norm returns the Euclidean 'L-2' norm for the values in the Data array. The 'L-2' norm is the square root of the sum of squares.
Note: In C++, Data is an array of values, and Data_Size is the index of the last value in the array (one less than the number of values).
