Description:
Calculate the Euclidean distance between two vectors.
Syntax:
dis(A,B)
Note:
The function gets the true straight line distance, the Euclidean distance, between vector A and vector B in an n-dimensional space.
By default, parameter B consists all of 0 and the function calculates the Euclidean distance between vector A and the origin.
Parameter:
|
A/B |
Vector |
Option:
|
@a |
Calculate the sum of absolute values of the differences between numbers at same positions in vector A and vector B |
|
@m |
Average out the Euclidean distance before getting its square root |
Return value:
Numeric value
