In vcastellar/fastDist: What the package does (short line)

fastDist

Cálculo rápido de distancias entre filas de dos matrices

benchmark

Tiempo (segundos) de cálculo de distancias entre filas de una matriz de dimensiones 10000x100. Comparación de diferentes métodos entre el paquete fastDist y el proxy. Para el test, se usa el paquete microbenchmark. Ejecutado en un procesador pentium i5 10400
