[Pharo-dev] About Matrix API access

Hi I'm wondering why | matrix23 | matrix23 := Matrix rows: 3 columns: 2. matrix23 at: 1 at: 1 put: 11. matrix23 at: 1 at: 2 put: 12. matrix23 at: 1 at: 3 put: 13. matrix23 at: 2 at: 1 put: 21. matrix23 at: 2 at: 2 put: 22. matrix23 at: 2 at: 3 put: 23. is not equivalent to | matrix23 | matrix23 := Matrix rows: 3 columns: 2. matrix23 atColumn: 1 atRow: 1 put: 11. matrix23 atColumn: 1 atRow: 2 put: 12. matrix23 atColumn: 1 atRow: 3 put: 13. matrix23 atColumn: 2 atRow: 1 put: 21. matrix23 atColumn: 2 atRow: 2 put: 22. ^ matrix23 atColumn: 2 atRow: 3 put: 23 I always thought that math notation was x,y (row,colum) How is it done in other languages? I checked the implementation so I know but why this choice in the API.
