Description
Returns the length, or magnitude, of the specified vector.
FUNCTION Norm(
Vec :VECTOR) : REAL;
def vs.Norm(Vec):
return REAL
Parameters
Vec VECTOR Vector to be measured.
Return Value
A REAL value which is the length of the vector.
Remarks
(_c_, 2022.01.20) In Python the vector used as parameter MUST be 3-dimensional, or it will return gibberish. This doesn't matter in Pascal.
Example
VectorScript
PROCEDURE Example;
VAR
vec :VECTOR;
BEGIN
vec.x := 1;
vec.y := 1.732050807;
Message(Norm(vec));
END;
RUN(Example);
PROCEDURE Example2;
VAR
v1, v2 : VECTOR;
BEGIN
v1.x := 12; v1.y := 1;
v2.x := 3; v2.y := 15;
Message( Norm(v1-v2) );
END;
Run(Example2);
Python
v1 = (12, 1, 0) # 3-dimensional tuple v2 = (3, 15, 0) vs.Message( str(vs.Norm( (v1[0] - v2[0], v1[1] - v2[1], v1[2] - v2[2]) )) )
