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:

Absolute value function

The absolute value function (ABS), when applied to a vector, produces the

magnitude of the vector. For a vector A = [A

], the magnitude is

AAAA +++= L . In the ALG mode, enter the function

name followed by the vector argument. For example: ABS([1,-2,6]),

ABS(A), ABS(u3), will show in the screen as follows:

The MTH/VECTOR menu

The MTH menu („´) contains a menu of functions that specifically to

vector objects:

The VECTOR menu contains the following functions (system flag 117 set to

CHOOSE boxes):
