Scalar Expansion (MATRIX-END MATRIX command)

When one of the matrices involved in an operation is a scalar, the scalar is treated as a matrix of the correct size in order to carry out the operation. This internal scalar expansion is performed for the following operations:

• Addition and subtraction.
• Elementwise multiplication, division, and exponentiation. Note that multiplying a matrix elementwise by an expanded scalar is equivalent to ordinary scalar multiplication--each element of the matrix is multiplied by the scalar.
• All relational and logical operators.
