PyOperators 0.7
What’s new ?
- Raising an operator to an integer exponent.
- New operator DifferenceOperator.
- New Variable class and X instance.
- Expose pcg function, instead of PCGAlgorithm
- In a composition, HomothetyOperator has a distinct and more efficient handling. It can now be absorbed by the operands.
- New composition rules for ReshapeOperator, real ConvolutionOperator, BlockSliceOperator, DenseOperator
- New class for the transpose of the real-kernel convolution (subclassing the real-kernel convolution), so that composition and addition rules can be applied to both the convolution and its transpose.
Under the hood:
- Fix todense for operators requiring aligned arrays.
- Use site.USER_BASE instead of ~/.local to store FFTW wisdom and make environment variable PYOPERATORSPATH override it.
- New lanczos implementation.
- Make EigendecompositionOperator subclass CompositionOperator
- API change: DistributionGlobalOperator->MPIDistributionGlobalOperator
