• This API is used to compute the inverse of the input square matrix.
• Formula:$${A}^{-1}A = A{A}^{-1} = {I}_{n}$$ $A$ is the input tensor, $A^{-1}$ is the inverse of $A$, and $I_n$ is the unit matrix of dimension $n$.

Each operator has calls. First, aclnnInverseGetWorkspaceSize is called to obtain the workspace size required for computation and the executor that contains the operator computation process. Then, aclnnInverse is called to perform computation.
