[ruby-core:84169] [Ruby trunk Feature#14151] Make Matrix#[]= public method

Issue #14151 has been updated by marcandre (Marc-Andre Lafortune). Thanks mame for the input. It's a tough case I think, in particular because matrices can be big and thus expensive to `dup`. Do you have any extra argument to keep Matrix immutable? An alternative solution could be a `MutableMatrix` class ---------------------------------------- Feature #14151: Make Matrix#[]= public method https://bugs.ruby-lang.org/issues/14151#change-68278 * Author: greggzst (Grzegorz Jakubiak) * Status: Feedback * Priority: Normal * Assignee: marcandre (Marc-Andre Lafortune) * Target version: ---------------------------------------- I don't even understand why this method hasn't been public since the beginning. I've come to a point when I have to create a matrix in a specific way using row and column indices and I can't use #build with a block because then indices go from the beginning of matrix whereas I have to from the center of the matrix. So what I wanted to do is to create a zero matrix and the fill it in a proper way but I can't without using #[]=. I know I can reopen class and that's what I'm doing but this just doesn't make sense. If we can change elements in an array like so using #[]= then why matrices can't use that as well? -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:[email protected]?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
