| Syntax: |
vout = >−v
|
The reflect operator, >−, is a unary operator that interchanges the
columns of a matrix.
Suppose the matrix M has N rows and M columns.
Then >−M is also an N by M matrix, but column 1 has been interchanged
with column M, column 2 has been interchanged with column M-1, and so on.
Examples
Suppose matrix M is
| 1 10 -1 |
M = | 2 20 -2 |
| 3 30 -3 |
| 4 40 -4 |
then
| -1 10 1 |
>-M = | -2 20 2 |
| -3 30 3 |
| -4 40 4 |
You can reflect the rows of a matrix, by using the reflect operator and the transpose operator.
Suppose M is as above. Then
| 4 40 -4 |
<-(>-(<-M)) = | 3 30 -3 |
| 2 20 -2 |
| 1 10 -1 |
