Issue #10073 has been reported by gogo tanaka. ---------------------------------------- Feature #10073: [PATCH] Implement Laplace expansion for matrix. https://bugs.ruby-lang.org/issues/10073 * Author: gogo tanaka * Status: Open * Priority: Normal * Assignee: * Category: * Target version: ---------------------------------------- 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) -- https://bugs.ruby-lang.org/
