Calculation of the matrix-vector products
Given the matrix
\[{}\]
and the vector `{}` (the blue arrow in the applet), their product is:
\[{}\]
The vector `{}` is represented by the dotted blue arrow in the applet.
The product of `{}` with the vector `{}` (the green arrow in the applet) is:
\[{}\]
The vector `{}` is represented by the dotted green arrow in the applet.
