Vectors
In addition to those in the Vector MATH menu, the following vector operations are
allowed. Dimensions must be correct:
• vector + vector
• vector – vector
• Scalar multiplication (for example, 2 × vector)
• matrix × vector (vector will be interpreted as a column vector)
% [vector] NAMES
% [vector] displays the vector NAMES menu, which shows the dimensions of the
vectors and lets you use them in calculations.
The dimension of a vector can be 1{dim{3.
1:[u] Definable vector [u]
2:[v] Definable vector [v]
3:[w] Definable vector [w]
4:[Ans] Last matrix result ([Ans]=row×column), or
last vector result ([Ans] dim=n).
Not editable.
Note: Cell values can be toggled. To view the full
precision or exact format, highlight the cell.
% [vector] MATH
% [vector] " displays the vector MATH menu, which lets you perform the following
vector calculations:
1:DotProduct Dot product of two vectors with the same
dimension.
Syntax: DotP(vector1,vector2)
2:CrossProduct Cross product of two vectors with the same
dimension.
Syntax: CrossP(vector1,vector2)
3:norm Norm (magnitude) of a vector.
