QUESTION

Eigen with custom scalar types: Matrix multiplication with custom type fails with `use of overloaded operator '*' is ambiguous`

Asked 2020-May-27 at 16:01

I am trying to integrate boost.units into Eigen, following the official documentation. I've also looked at two projects that have done the same, and I've tested the operation with their code as well, although I'm getting the same error (Project 1 Project 2).

The issues I am having is that there seems to be some ambiguity regarding the multiplication operator when multiplying two matrices with custom scalar types based on boost::units.

This behaviour occurs with clang 10.0.0.3 and Apple clang 11.0.3.

The code that triggers the error (use of overloaded operator '*' is ambiguous) is the following:

Ignoring the conjugate product traits, I can see that the third specialization seems off:

QUESTION

Custom scalar type in Eigen

Asked 2020-Jan-16 at 07:54

I'm currently trying to set up a custom scalar type for use with the Eigen3 library (atm it is a simple wrapper around double). I have followed https://eigen.tuxfamily.org/dox/TopicCustomizing_CustomScalar.html to the best of my knowledge and the basic things work fine.

I need to solve eigenvalue-problems for the matrices with my custom type though and this is exactly where things start falling apart. My compiler spits the following error message at me:

Marc Glisse pointed out that my operator-overloads appeared to be kinda weird, so I rewrote them and the initial issue was gone. I don't have a clue as of why exactly this is the case though.

Then I only had the problem that Eigen's isfinite function was not defined for my custom type, so I went ahead and added an implementation of it as well (though I'm not sure if that is actually a solid one).

Anyways my code compiles now. Here's the modified version of my code:

Install numtraits

You can install using 'pip install numtraits' or download it from GitHub, PyPI.
You can use numtraits like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
