Class Numbers of Real Quadratic Fields
Computes class numbers h(d) for fundamental discriminants d using continued fraction regulator + Euler product L(1, chi_d).
Usage
import torch
from kernels import get_kernel
kernel = get_kernel("cahlen/class-numbers-cuda")
result = class_numbers.compute(discriminants)
Compile (standalone)
nvcc -O3 -arch=sm_90 -o class_numbers class_numbers/class_numbers_v2.cu -lm
