I am a novice in nonparametric modeling and have recently begun exploring the world of varying coefficient models. Essentially, these models involve a non-linear least squares problem that relies on kernel weights. My current challenge is the slow performance of my R code, which is the only programming language I am fa... |
I see three complexities in accessing (reading/writing) integer field in network packet.
Handle endianness. Integer in network packet is big-endian (BE). The host may be either big-endian or little-endian (LE).
The integer may have a bit width that is not a multiple of 8. E.g., IPv4 fragment offset has 13 bits.

I am learning object oriented programming in Rust. I created my own struct for complex numbers. Could you please review and answer my questions:
Is it possible to implement C++-like default constructor? I want to replace let c0 = my_math::Complex::default(); with let c0: Complex;.
Why should I implement PartialEq ins... |
This is supposed to subdivide a n-dimensional aabb (axis aligned bounding box) into 2ⁿ equal pieces as if sliced by n planes that are perpendicular to only one axis and parallel to the rest of the axes at a time.
The code:
CGL_bool CGL_aabb_subdivide_ndim(CGL_int n, CGL_float* aabb_min, CGL_float* aabb_max, CGL_float* ... |
