| Version | Published | Release Notes | Action |
|---|---|---|---|
| 3.0.0 | I just learned about the paged matrix functions from Mike Croucher's blog and immediately replaced backslash with pagemldivide for a significant speedup. |
||
| 2.0.0 | This version uses implicit expansion (or bsxfun in slightly older MATLAB versions) to compute the line segments that might overlap. When the number of line segments is large, it uses a different algorithm to avoid forming large matrices. |
||
| 1.2.0 | Fixed bug that my previous "bug fix" failed to fix. |
||
| 1.1.0 | Fixed bug identified by Rodrigo Portugal. No longer fails when there are no intersections and you need 4 outputs. |
||
| 1.0.0 | Added ability to find self-intersections of one curve. |
