Scalar Operations
Scalar operations perform arithmetic operations between a scalar (that is, a
number) and each element of a matrix. The scalar and the descriptor of the
matrix must be placed in the X- and Y-registers – in either order. (Note that
the register position will affect the outcome of the - and ÷ functions.)
The resulting values are stored in the corresponding elements of the result
matrix.
The possible operations are shown in the following table.
