Issue #10073 has been updated by Marc-Andre Lafortune. Status changed from Assigned to Closed Great, thanks for the updated patch. ---------------------------------------- Feature #10073: [PATCH] Implement Laplace expansion for matrix. https://bugs.ruby-lang.org/issues/10073#change-49268 * Author: gogo tanaka * Status: Closed * Priority: Normal * Assignee: Marc-Andre Lafortune * Category: lib * Target version: current: 2.2.0 ---------------------------------------- Laplace expansion has really important mathematical property. We can handle many thing with this (determinant, cross product) So I'm confident that this method is necessary. But I recognize Ruby should be not for mathematician but rubyist. Ruby doesn't need too academic method. So If you think it is too academic you can ignore my patches. gogo. ---Files-------------------------------- implement_Matrix#laplace_expansion.patch (3.31 KB) add_test_for_laplace_expansion.patch (1.78 KB) update_news.patch (772 Bytes) implementing_laplace_expansion.patch (1.81 KB) -- https://bugs.ruby-lang.org/
