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
1
,A
2
,…,A
n
], the magnitude is
defined as
222
||
zyx
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):
