Janardhan commented on SYSTEMML-1931: ------------------------------------- Resolved by [~mboehm7]. & commit address: https://github.com/apache/systemml/commit/ea77cb456008c99276ebbae021ea8fe1246338ea > Support logical operators AND, OR, XOR, NOT over matrices > --------------------------------------------------------- > > Key: SYSTEMML-1931 > URL: https://issues.apache.org/jira/browse/SYSTEMML-1931 > Project: SystemML > Issue Type: Bug > Reporter: Matthias Boehm > Assignee: Matthias Boehm > > So far, all logical operators (AND, OR, XOR, NOT) are only supported over > scalars. This task aims to add support for logical operators over matrices. > In detail, this entails: > * New test cases for all logical operators over dense and sparse matrices and > CP, MR, and SPARK execution types. > * Parser/compiler integration: (a) validation of boolean expressions to check > the validity of inputs (scalar or matrices), (b) propagation of data type and > value types (double if at least one matrix input), (b) sparsity estimates for > the individual operators. > * Runtime integration: Extend the function objects of AND, OR, XOR, NOT to > combinations of double, and boolean inputs. > * Fix (extend) opcode checks of individual instructions. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
