Abstract: The error bounds of the solutions to the extended vertical linear complementarity problem are studied for the CKV-type matrix and the CKV-type-B matrix.Under the premise that "any sub-block of the block matrix satisfies the definition of the two types of matrices",it is proved that after row rearrangement of the original block matrix,each sub-block of the new matrix still maintains the same type as the original matrix sub-block,and the rearranged matrix has the row W-property.On this basis,the error bound expressions of the solutions to the problems corresponding to the two types of matrices are derived.
