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)| Name | Type | Description |
|---|---|---|
| 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. |
(_c_, 2022.01.19) In VS Python the tuples v1 and v2 must be 3-dimensional, or the function will return gibberish.
(_c_, 2010 Dec. 22) See graphical representation of how '''Comp''' works (click on the image to enlarge it):
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);v1 = (12, 1, 0) # 3-dimensional tuples
v2 = (3, 15, 0)
v3, v4 = vs.Comp( v1, v2 )
vs.Message(str(v3) + '\r' + str(v4))Availability: from All Versions
