Extends from Modelica.Icons.Function (Icon for functions).
Information
Syntax
Vectors.length(v);
Description
The function call "Vectors.length(v)" returns the
Euclidean length "sqrt(v*v)" of vector v.
The function call is equivalent to Vectors.norm(v). The advantage of
length(v) over norm(v)"is that function length(..) is implemented
in one statement and therefore the function is usually automatically
inlined. Further symbolic processing is therefore possible, which is
not the case with function norm(..).
Example
v = {2, -4, -2, -1};
length(v); // = 5
