All of these should be replaced by proper references using the `:ref:` Sphinx role, or, for most links to the reference manual, using `:mod:`, `:func:`, :class:` etc.
When there is no label that ca…

https://en.wikipedia.org/wiki/Ray_transfer_matrix_analysis is a good start. However, it only captures radial symmetry. Electron optics are generally not symmetric. The following properties are desirab…

Currently, Matrix_double_dense inherits from Matrix_dense and Matrix_double_sparse from Matrix_sparse. However numerical matrices share a lot compared to other matrices and should probably have a co…

I talked to Moritz Diehl last week about this idea and he asked me to contact you directly:
One of CasADi's strengths is the plethora of algorithms you can invoke with just a few commands. As a con…

http://docs.scipy.org/doc/scipy-0.17.0/reference/generated/scipy.sparse.linalg.cg.html (and other solvers too) currently defines the preconditioner M as "The preconditioner should approximate the inve…

## Description of the issue
As described in https://github.com/OpenEnergyPlatform/ontology/issues/859 most of the individuals in the OEO are lacking a definition.
In addition the upper classes are…

The current module organization in SymPy is far from optimal. The "core" is
too big (several hundred kilobytes of code, much unrelated functionality
thrown in one place), and some closely related …

The examples folder has several algorithms that mix the `DataBag` abstraction with linear algebra. Currently, we use Breeze, but we might switch to something else if we agree that it is better.
Let'…

Suppose we want to solve a system $Ax = b$, where $A$ is a [polynomial matrix](https://en.wikipedia.org/wiki/Polynomial_matrix) and $b$ is a vector of polynomials. ModelKit seems to be unable to solve…

It would be good to have numerical integration and differentiation. Integration would be using the Newton–Cotes formulas, and differentiation by the Symmetric derivative.
