14f0fde51f Add certain functions to numext (log, exp, tan) because CUDA doesn't support std:: 
Use these in SpecialFunctions.

0bb5de05a1 Finishing touches on igamma/igammac for GPU. Tests now pass. 2016-03-07 15:35:09 -08:00

5707004d6b Fix Eigen's building of sharded tests that use CUDA & more igamma/igammac bugfixes. 
0. Prior to this PR, not a single sharded CUDA test was actually being *run*.
Fixed that.

GPU tests are still failing for igamma/igammac.

1. Add calls for igamma/igammac to TensorBase
2. Fix up CUDA-specific calls of igamma/igammac
3. Add unit tests for digamma, igamma, igammac in CUDA.

0b9e0abc96 Make igamma and igammac work correctly. 
This required replacing ::abs with std::abs.
Modified some unit tests.

2de8cc9122 Merged in ebrevdo/eigen (pull request PR-167) 
Add infinity() support to numext::numeric_limits, use it in lgamma.

I tested the code on my gtx-titan-black gpu, and it appears to work as expected.

6afea46838 Add infinity() support to numext::numeric_limits, use it in lgamma. 
This makes the infinity access a __device__ function, removing
nvcc warnings.
