"OpenMG" (lets shorten that more: "OMG") allows the user to sample scattering angles from the provide legendre polynomials described the scattering moment matrices as a non-default option. This is cu…

FFTW allows specifying "regions", for multidimensional FFTs:
```julia
julia> X = randn(5,5,5);
julia> F = fft(X,(1,3));
julia> F[:,1,:] ≈ fft(X[:,1,:]) # 2D FFT acting on 1st and 3rd dimension…

Hi, I am trying to analyze the energy at different scales from a set of simulations based on this nice model. So how could I do this on the spherical earth?
I know I could do FFT along the zonal d…

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…

objects should be created through the object factory using the .create method and modification of those objects should work with a .method.

I think it would be good to have convenient acces to the dimensionality of a CellValues object. Especially when someone chooses to use a Scalar CellValues object instead of a Vector CellValues object …

# The issue
The `phicurve` function counts the number of crossings with the number of sign changes (line 40). Therefore, when a vertex sits on the colatitude at where crossings are evaluated, the num…

I'm getting junk line map info from SymtabAPI on a gcc 8.1 compiled object file. I wrote a small symtab reproducer that opens my object file and prints the line info associated with a few addresses:
