相对误差容差，指定为正实数。默认为1e-6。这RELTOL.argument determines the accuracy of the integration only if $$RelTol·\left|Q\right|>AbsTol$$, whereQis the calculated integral. In this case,vpaintegralsatisfies the condition $$\left|Q-I\right|\le RelTol·\left|Q\right|$$, whereI是确切的积分价值。只使用RELTOL.和turn offAbsTol, setAbsTolto0。

例子：1e-8

Absolute error tolerance, specified as a non-negative real number. The default is1e-10。AbsTol确定集成的准确性 $$AbsTol>RelTol·\left|Q\right|$$, whereQis the calculated integral. In this case,vpaintegralsatisfies the condition $$\left|Q-I\right|\le AbsTol$$, whereI是确切的积分价值。To turn offAbsTol并仅使用RELTOL., setAbsTolto0。

例子：1e-12

集成路径, specified as a vector of numbers, or as a vector of symbolic numbers, expressions, or functions.vpaintegral㈡egrates along the sequence of straight-line paths (lower limit to the first waypoint, from the first to the second waypoint, and so on) and finally from the last waypoint to the upper limit. For contour integrals, set equal lower and upper limits and define the contour using waypoints.

输入的最大评估, specified as a positive integer or a positive symbolic integer. The default value is10 ^ 5.。如果评估的数量f大于MaxFunctionCalls, thenvpaintegral抛出错误。对于无限制的评估，设置MaxFunctionCallstoinf。
