[object Object]

[object Object][object Object]undefined[object Object]

• Function: Returns the value of the error function corresponding to each element in the input tensor.
• Formula:

$$erf(x)=\frac{2}{\sqrt{\pi } } \int_{0}^{x} e^{-t^{2} } \mathrm{d}t$$ [object Object]

[object Object] and [object Object] implement the same function in different ways. Select a proper operator based on your requirements.

• [object Object]: An output tensor object needs to be created to store the computation result.
• [object Object]: No output tensor object needs to be created, and the computation result is stored in the memory of the input tensor.

Each operator is divided into two phases (../common/twp-phase_api.md). You must call aclnnErfGetWorkspaceSize or aclnnInplaceErfGetWorkspaceSize to obtain the workspace size required for computation and the executor that contains the operator computation process, and then call aclnnErf or aclnnInplaceErf to perform the computation.
