+Check whether the Tensor is a coalesced SparseCooTensor. If not it will return False.
+Tensor types other than SparseCooTensor are not supported.
+
+Notes:
+    It will return always False for a newly created SparseCooTensor.
+
+Args:
+    x (Tensor): The input tensor. It can only be SparseCooTensor.
+
+Returns:
+    bool: True if the Tensor is a coalesced SparseCooTensor, and False otherwise.
+
+Examples:
+
+    .. code-block:: python
+
+        >>> import paddle
+
+        >>> indices = [[0, 0, 1], [1, 1, 2]]
