两个命令的区别具体是什么？

tuoni

Bem=@(y,x,z)(1.18*10^5)*(b-x)/(sqrt((a-y)^2+(b-x)^2+(c-z)^2));这是积分方程，
) \" [9 |% ^1 G- d" E9 u" I用q = integral3(Bem(y,x,z),-0.015,0.015,-0.015,-0.0065,0,0.01)可以进行运算；
1 B& V" J- {0 S% i" o) h但是用q = triplequad(Bem(y,x,z),-0.015,0.015,-0.015,-0.0065,0,0.01)不能运行，
7 p  a' e7 F9 G" v. ^显示错误：输入必须为单精度或双精度浮点值。请问两个命令的区别具体是什么？
% g; I1 F/ n  \5 O6 \- P- T2 O非常感谢！

没什么不能用的啊
