Multiplies an array of numbers by a scalar or another array of numbers.
Note
Since Arma 3 v2.14: Since Arma 3 v2.14 any count of numbers is valid, if one array is larger than the other, the remaining elements are inserted without change.
Before Arma 3 v2.14, the first argument had to be vector 3D, or Arma 3 v2.00 2D (Which still returned 3D result, with z coordinate defaulted to 0)

Parameters:
numArray: Array of Numbers - an array of any size to be multiplied with the multipliermultiplier: Number or Arma 3 v2.14 Array of Numbers_newVector = [1,2,3] vectorMultiply 3; // returns [3,6,9]
[1,2,3,4] vectorMultiply [1,2,3,4]; // [1,4,9,16]
[1,2,3,4] vectorMultiply 2; // [2,4,6,8]
[1,2,3,4] vectorMultiply [2]; // [2,2,3,4]
[2] vectorMultiply [1,2,3,4]; // [2,2,3,4]
[1,2,3] vectorMultiply [1,2,3,4,5]; // [1,4,9,4,5]
private _eyePos = eyePos player;
private _eyeDir = getCameraViewDirection player; // this is a normalized vector, i.e. its magnitude is 1
private _100mFurther = _eyeDir vectorMultiply 100; // since _eyeDir is normalised (length = 1m), multiplying it by 100 means 100m in that direction
private _lookPos = _eyePos vectorAdd _100mFurther; // the position where player is looking 100m ahead
// Override firing to throw the player towards where he's aiming

Arma 3 v1.22 Algorithm:
Vector = [x, y, z]; scalar = a;
Result = [(x * a), (y * a), (z * a)];
It is recommended to use vectorMultiply instead of BIS_fnc_vectorMultiply. This is a very useful function, as it can be used with the velocity command to move an object from one position to another. (ie <vector1> to <vector2>) - ensure both positions are found using getPosASL.
_obj setVelocity (((getPosASL _target) vectorDiff (getPosASL _obj)) vectorMultiply 2);
