Matrix1 .+ Matrix2 ⇒ matrix
Expr .+ Matrix1⇒ matrix
Matrix1.+Matrix2 returns a matrix that is
the sum of each pair of corresponding
elements in Matrix1 and Matrix2.
Expr .+ Matrix1 returns a matrix that is
the sum of Expr and each element in
Matrix1.

Expr .− Matrix1 ⇒ matrix
Matrix1.− Matrix2 returns a matrix that is
the difference between each pair of
corresponding elements in Matrix1 and
Matrix2.
Expr .− Matrix1 returns a matrix that is
the difference of Expr and each element in
Matrix1.
