Webb6 apr. 2024 · matlab好像可以把误差容限调到10^-7以下,而c++则只能到10^-5左右。原因不甚了解,猜测可能是由于c++计算时字节长度不够,导致精度不够,要递归调用很多次才能达到所需精度。 WebbCalculer des intégrales de manière numérique et symbolique. Une intégrale est un résultat mathématique représentant l'aire située entre une fonction et un plan (par exemple, un plan x-y). Le concept d'intégrale est fondamental en calcul. Son application s'étend de manière assez large à toutes les disciplines d'ingénierie.
