PyOperators 0.4
What’s new ?
- new operators BlockSliceOperator, HardThresholdingOperator and SoftThresholdingOperator
- add commin and commout as operator’s attribute, to deal with input and output communicators. Handling of implicit communicators. Add propagation mechanism.
- add MPI helper functions combine, distribute, distribute_shapes, mprint, filter_comm, as_mpi
- add function product
- when combined with a block operator, split DiagonalOperators and ConstantOperators
- add operator’s flag ‘universal’, used in rules involving operators and block operators
- infer implicit partition during addition, multiplication or composition
- binary rule for DiagonalOperator and BlockOperator, including broadcasting
- API change: broadcasting method is now ‘leftward’ or ‘rightward’
- implement Operator’s eq
- automatically set ‘inplace’ flag for ufuncs
- make BlockRowOperator handle arbitrary reduction operation, optimize direct method by using the memory manager
- automatic morphing of DiagonalOperator into IdentityOperator, ZeroOperator, HomothetyOperator or MaskOperator according to diagonal values
- fix involutary flag in DiagonalOperators
- add simplification fules: op + O -> op and op x I -> op
