Hello everyone!

I am new to Rust and new to nalgebra as well.

I am having problem with returning the type Matrix3 from a function.

Suppose I have this:

```
fn calculate( a: f64, b:f64) -> Matrix3 {
//calculations here
let m = Matrix3::new(values);
return m
}
```

I think I might have misunderstood something because I get the following error:

**error[E0107]** **: wrong number of type arguments: expected 1, found 0**

Can someone help me?
