AB - <p style="text-align: justify;">A semi-tensor product of matrices is proposed as a generalization of usual
matrix product in the case where the dimensions of two factor matrices do not match.
The properties of the semi-tensor product of tensors and swap tensors based on the Einstein product are studied. Applications of this new tensor product in image restoration
and in finite dimensional algebras are discussed.</p>
