It is useful and important when we handle linear equations, statistics and so on. ``` Matrix[[1, 2], [3, 4]].row_merge(Matrix[[5], [6]]) => 1 2 5 3 4 6 Matrix[[1, 2], [3, 4]].column_merge(Matrix[[5, 6]]) => 1 2 3 4 5 6 # accept more than two matrices as an argument. Matrix[[1, 2], [3, 4]].column_merge(Matrix[[5, 6]], Matrix[[7, 8]]) => 1 2 3 4 5 6 7 8 ``` * Matrix#row_merge needs Matrix#column ---Files-------------------------------- Implement_Matrix#column_merge.patch (863 Bytes) Add_test_for_Matrix#column_merge.patch (1.36 KB) Add_Matrix#column_merge_to_NEWS.patch (452 Bytes) Implement_Matrix#row_merge.patch (899 Bytes) Add_test_for_Matrix#row_merge.patch (1.4 KB) Add_Matrix#row_merge_to_NEWS.patch (523 Bytes) -- https://bugs.ruby-lang.org/
