Up: Matrix representation of loop transformations
Previous: Example: loop given earlier
We can also represent loop interchange by a matrix transformation.
After transforming the skewed loop by matrix
(i.e. loop interchange) we get:
- Distance: (1,1), direction: (<,<)
- Distance: (1,0), direction: (<,.)
The transformed iteration space is the transpose of the skewed
iteration space:
