Matrix Representation of Vectors
Vectors
are represented as
\(N \times 1\) Column Matrices
or as
Transpose of \(1 \times N\) Row Matrices
, where \(N\) is the
Number of Vector Components
. The following shows
Vector
\(V\) represented as a
Column Matrix
and a
Row Matrix
\(V=\begin{bmatrix}v_1\\v_2\\v_3\\v_4\\ \vdots \\v_n \end{bmatrix}=\begin{bmatrix}v_1 & v_2 & v_3& v_4 & \ldots & v_n\end{bmatrix}^T\)
Any
Vector \(V\) having 3 Components
can also be represented as a
Skew Symmetric Matrix
(denoted by \(V_\times\)) as follows
\(V=\begin{bmatrix}v_1 \\ v_2 \\ v_3\end{bmatrix}\hspace{6mm}\Rightarrow V_\times=\begin{bmatrix}0 & -v_3 & v_2 \\v_3 & 0 & -v_1 \\-v_2 & v_1 & 0\end{bmatrix}\)
The
Skew Symmetric representation can be used to calculate
Cross Product of Vectors
in form of
Matrix Multiplication
