• Description: Computes the symbolic value of each tensor in the input tensor list.

• Formula:

  $$x = [{x_0}, {x_1}, ... {x_{n-1}}]\\ y = [{y_0}, {y_1}, ... {y_{n-1}}]\\$$ $$y_i = \left\{ \begin{aligned} 1,\quad x_i > 0\\ 0,\quad x_i = 0\\ -1,\quad x_i < 0 \end{aligned} \right. \quad {,(i=0,1,...n-1)}$$

Each operator has calls. First, aclnnForeachSignGetWorkspaceSize is called to obtain the input parameters and compute the required workspace size based on the process. Then, aclnnForeachSign is called to perform computation.
