Dear Sir,

Since a few days I’m trying to incorporate nalgebra in my application. But I am unable to figure out how to get the magnitude(modulus) of a vector in a scalar format.

My code:

`let vector = Vector2::new(0.,0.); let modulus = abs(vector);`

The error I’m getting is :

`the trait bound 'nalgebra::Matrix<f64, nalgebra::U2, nalgebra::U1, nalgebra::MatrixArray<f64, nalgebra::U2, nalgebra::U1>>: num_traits::sign::Signed' is not satisfied.`

Am I missing a step when creating the vector?

Sincerely,

Wooter
