MAG
The MAG function returns the magnitude of an arbitrary vector function expression.
Format
MAG(exp)
Arguments
exp | An arbitrary vector function expression. |
Extended Definition
Mathematically, MAG is calculated as:
where 
is an arbitrary vector function expression.
is an arbitrary vector function expression.Examples
VARIABLE/1, FUN=MAG(VXYZ(i,j))
VARIABLE/2, FUN=SQRT(VXYZ(i,j)*VXYZ(i,j))
VARIABLE/3, FUN=VM(i,j)
VARIABLE/2, FUN=SQRT(VXYZ(i,j)*VXYZ(i,j))
VARIABLE/3, FUN=VM(i,j)
Variables 1, 2 and 3 are synonymous. They all compute the magnitude of the relative velocity of markers i and j.
