vec_sub

Purpose

Returns a vector containing the result of subtracting each element of b from the corresponding element of a.

Syntax

d=vec_sub(a, b)

Result and argument types

The following table describes the types of the returned value and the function arguments.

d	a	b
`vector4double`	`vector4double`	`vector4double`

Result value

The value of each element of the result is the result of subtracting the value of the corresponding element of b from the value of the corresponding element of a.

Formula

d[0] = a[0] - b[0]
d[1] = a[1] - b[1]
d[2] = a[2] - b[2]
d[3] = a[3] - b[3]

Example

a =  (50.0, 60.0, 70.0, 80.0)
b =  (10.0, 20.0, 30.0, 40.0)
d: (40.0, 40.0, 40.0, 40.0)
