Example fail to run?

[Spammed]

Perhaps a Rust beginner's mistake.
I do not get the example to work but get:

assert_matrix_eq!(csr, dense);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|     the trait `matrixcompare::Matrix<_>` is not implemented for `CsrMatrix<{float}>`   
|     required by a bound introduced by this call

As dependecies i have

[dependencies]
approx = "0.5.1"
nalgebra = "0.32.1"

nalgebra-sparse = "0.9"
matrixcompare = "0.3.0"

What else do I need to do?

Hi, this is perhaps not so clear from the documentation, but using the matrixcompare functionality requires the compare feature enabled, so that you have to write

nalgebra-sparse =  { version="0.9", features = [ "compare" ] }

Similarly, you have to do the same with nalgebra if you want to compare dense vectors/matrices.

Thank you very much. It works.
