基于matlab计算人体皮肤表面温度随时间变化的曲线。(Matlab calculation based on human skin surface temperature over time curve.)

Matlab est un langage simple et très efficace, optimisé pour le traitement des matrices, d’où son nom. Pour le calcul numérique, Matlab est beaucoup plus concis que les “vieux” langages (C, Pascal, Fortran, Basic). Un exemple: plus besoin de programmer des boucles modifier pour un à un les éléments d’une matrice. On peut traiter la matrice comme une simple variable. Matlab contient également une interface graphique puissante, ainsi qu’une grande variété d’algorithmes scientifiques.
