At the moment just the Chebyshev polynomials are symbolic. Missing are `hermite`, `laguerre`, `legendreP`, `legendreQ`, `ultraspherical` (=`gegenbauer`), and, while the Stirling and Euler polynomial…

The Legendre polynomials, returned by `legendre_P()`, of the first kind are orthogonal over [-1,1] and are normalized to have value +-1 at the endpoints.
When solving least-squares problems, it's c…

I was fitting some polynomials using [numpy.polyfit](http://docs.scipy.org/doc/numpy/reference/generated/numpy.polyfit.html) with `cov=True` to get the covariance of the fitted parameters.
I wanted t…

In the test directory, include code function values of different polynomials as tests to verify answers are correct.
I have yet to find a more efficient method than copy pasting the [pdf archives](ht…

Hi, thank you for the tutorial, please I have a question about the example on multiple lactations . In the file line 11 to 16 indicating the two lactations, please can you specify what kind of data th…

Li2020 contains a fairly up to date set of numerical methods for fractional derivatives and integrals.
It would be very cool to implement most of this and compare.

Reported by László Oroszlány and Laszlo Szunyogh.
There is a small mistake (or just rather an inconsistency) in the way you define the c-type Gaunt coefficients in the section about Legendre Polynomi…

I ran into a `StackOverflowError` when using symbolic polynomials with SymPy.jl and Polynomials.jl.
The reason seems to be related to arrays of `Sym` and scalars of type `Sym` having different (eleme…

I'm finding that if I'm at high multipoles and high elevation, at some point the legndre polynomials seem to maybe underflow, so it becomes all zeros?
