The principal square root function is defined using the nonpositive real axis as a branch cut.
主平方根函数是使用非正实轴作为分支切割定义的。
It can be applied to solve nonpositive definite or positive definite partial differential equation with arbitrary variable coefficient under arbitrary boundary condition.
它可以求解在任意边界条件下任意变系数正定或非正定偏微分方程。
