* Implement scalar multiples and division by a scalar as a binary-expression ↵Gravatar Gael Guennebaud2016-06-14
| | | | | | | | | | | | with a constant expression. This slightly complexifies the type of the expressions and implies that we now have to distinguish between scalar*expr and expr*scalar to catch scalar-multiple expression (e.g., see BlasUtil.h), but this brings several advantages: - it makes it clear on each side the scalar is applied, - it clearly reflects that we are dealing with a binary-expression, - the complexity of the type is hidden through macros defined at the end of Macros.h, - distinguishing between "scalar op expr" and "expr op scalar" is important to support non commutative fields (like quaternions) - "scalar op expr" is now fully equivalent to "ConstantExpr(scalar) op expr" - scalar_multiple_op, scalar_quotient1_op and scalar_quotient2_op are not used anymore in officially supported modules (still used in Tensor)
* Relax mixing-type constraints for binary coefficient-wise operators:Gravatar Gael Guennebaud2016-06-06
| | | | | | | | | | - Replace internal::scalar_product_traits<A,B> by Eigen::ScalarBinaryOpTraits<A,B,OP> - Remove the "functor_is_product_like" helper (was pretty ugly) - Currently, OP is not used, but it is available to the user for fine grained tuning - Currently, only the following operators have been generalized: *,/,+,-,=,*=,/=,+=,-= - TODO: generalize all other binray operators (comparisons,pow,etc.) - TODO: handle "scalar op array" operators (currently only * is handled) - TODO: move the handling of the "void" scalar type to ScalarBinaryOpTraits
* Add randomized properties tests for betainc special function.Gravatar Eugene Brevdo2016-06-05

* Add TernaryFunctors and the betainc SpecialFunction.Gravatar Eugene Brevdo2016-06-02
| | | | | | | | | | | | | | | | | | | TernaryFunctors and their executors allow operations on 3-tuples of inputs. API fully implemented for Arrays and Tensors based on binary functors. Ported the cephes betainc function (regularized incomplete beta integral) to Eigen, with support for CPU and GPU, floats, doubles, and half types. Added unit tests in array.cpp and cxx11_tensor_cuda.cu Collapsed revision * Merged helper methods for betainc across floats and doubles. * Added TensorGlobalFunctions with betainc(). Removed betainc() from TensorBase. * Clean up CwiseTernaryOp checks, change igamma_helper to cephes_helper. * betainc: merge incbcf and incbd into incbeta_cfe. and more cleanup. * Update TernaryOp and SpecialFunctions (betainc) based on review comments.
