Simple operations with vectors

To illustrate operations with vectors we will use the vectors A, u2, u3, v2, and

v3, stored in an earlier exercise.

Changing sign

To change the sign of a vector use the key \, e.g.,

Addition, subtraction

Addition and subtraction of vectors require that the two vector operands have

the same length:

Attempting to add or subtract vectors of different length produces an error

message (Invalid Dimension), e.g., v2+v3, u2+u3, A+v3, etc.

Multiplication by a scalar, and division by a scalar

Multiplication by a scalar or division by a scalar is straightforward:
