两个命令的区别具体是什么？

6 {8 H9 J9 T3 ^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，
, d1 a& i/ v; }' u( N: T用q = integral3(Bem(y,x,z),-0.015,0.015,-0.015,-0.0065,0,0.01)可以进行运算；
但是用q = triplequad(Bem(y,x,z),-0.015,0.015,-0.015,-0.0065,0,0.01)不能运行，
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？
