Description

Description:: Subtracts one 3D vector from another. (vector1 - vector2)

2.14
Since 2.14 any count of numbers is valid, if one array is larger than the other, the remaining elements are inserted without change.
Before 2.14, the first argument had to be vector 3D, or 2.00 2D (Which still returned 3D result, with z coordinate defaulted to 0)
Groups:: Math - Vectors

Syntax

Syntax:: vector1 vectorDiff vector2
Parameters:: vector1: Array of Numbers
: vector2: Array of Numbers
Return Value:: Array

Examples

Example 1:: Copy
hint str (velocity car vectorDiff velocity bike);

Additional Information

: 1.22 Algorithm:
Copy
Vector1 = [x1,y1,z1]; Vector2 = [x2,y2,z2]; Result = [x1 - x2, y1 - y2, z1 - z2];
It is recommended to use vectorDiff instead of BIS_fnc_vectorDiff.
