Description

Returns the components of a comparison of two vectors.

The vector component of v1 along v2 in v3, and the vector component of v1 orthogonal to v2 in v4.

PROCEDURE Comp(
        v1       :VECTOR;
        v2       :VECTOR;
        VAR v3   :VECTOR;
        VAR v4   :VECTOR);

def vs.Comp(v1, v2):
    return (v3, v4)

Parameters

v1	VECTOR	Comparison vector 1.
v2	VECTOR	Comparison vector 2
v3	VECTOR	Component of vector 1 along vector 2
v4	VECTOR	Component of vector 1 orthogonal to vector 2.

Remarks

(_c_, 2022.01.19) In VS Python the tuples v1 and v2 must be 3-dimensional, or the function will return gibberish.

Example

VectorScript

PROCEDURE Example;
VAR
    v1, v2, v3, v4 : VECTOR;
BEGIN
    v1.x := 12; v1.y := 1; { vector can be bidimensional without failure }
    v2.x := 3; v2.y := 15;
    Comp( v1, v2, v3, v4 );
    Message(Concat( v3, Chr(13), v4 ));
END;
Run(Example);

Python

v1 = (12, 1, 0) # 3-dimensional tuples
v2 = (3, 15, 0)
v3, v4 = vs.Comp( v1, v2 )
vs.Message(str(v3) + '\r' + str(v4))
