- paddle. inverse ( x, name=None )
Takes the inverse of the square matrix. A square matrix is a matrix with the same number of rows and columns. The input can be a square matrix (2-D Tensor) or batches of square matrices.
x (Tensor) – The input tensor. The last two dimensions should be equal. When the number of dimensions is greater than 2, it is treated as batches of square matrix. The data type can be float32 and float64.
name (str, optional) – The default value is None. Normally there is no need for user to set this property. For more information, please refer to Name
- A Tensor holds the inverse of x. The shape and data type
is the same as x.
- Return type
