> 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.
