+    Generates coordinate matrices from given coordinate tensors.

+    Given N one-dimensional coordinate tensors, returns a list outputs of N N-D
+    coordinate tensors for evaluating expressions on an N-D grid.
+
+
+    Args:
+        indexing (str): Either 'xy' or 'ij'. Default: 'xy'.
+        When the indexing argument is set to 'xy' (the default),

+
+    Inputs:
+        - **input_x** (Union[tuple, list]) - A Tuple or list of N 1-D Tensor objects.
+          The length of input_x should be greater than 1
+
+    Outputs:
+        Tensors, A Tuple of N N-D Tensor objects.
