This function fill the value into the x Tensor’s diagonal inplace. :param x: x is the original Tensor :type x: Tensor :param value: value is the value to filled in x :type value: Scale :param offset: the offset to the main diagonal. Default: 0 (main diagonal). :type offset: int,optional :param wrap: the diagonal ‘wrapped’ after N columns for tall matrices. :type wrap: bool,optional :param name: Name for the operation (optional, default is None) :type name: str,optional

Returns

Tensor with diagonal filled with value.

Return type

Tensor

Returns type:

dtype is same as x Tensor
