| | | | | | {uint8, int8} -> {int16, uint16, int32, uint32, float} {uint16, int16} -> {int32, uint32, int64, uint64, float} for NEON. These conversions were advertised as vectorized, but not actually implemented.

* CommaInitializer wrongfully asserted for 0-sized blocksGravatar Christoph Hertzberg2020-04-13
| | | | commainitialier unit-test never actually called `test_block_recursion`, which also was not correctly implemented and would have caused too deep template recursion.
* Fixed commainitializer test.Gravatar Antonio Sanchez2020-04-10
| | | | | | The removed `finished()` call was responsible for enforcing that the initializer was provided the correct number of values. Putting it back in to restore previous behavior.

* Replace norm() with squaredNorm() to address integer overflowsGravatar Antonio Sanchez2020-04-07
| | | | | | | | | | | For random matrices with integer coefficients, many of the tests here lead to integer overflows. When taking the norm() of a row/column, the squaredNorm() often overflows to a negative value, leading to domain errors when taking the sqrt(). This leads to a crash on some systems. By replacing the norm() call by a squaredNorm(), the values still overflow, but at least there is no domain error. Addresses https://gitlab.com/libeigen/eigen/-/issues/1856

* Add numeric_limits min and max for boolGravatar Akshay Naresh Modi2020-04-06

* Bugfix: conjugate_gradient did not compile with lazy-evaluated RealScalarGravatar Bernardo Bahia Monteiro2020-03-29
| | | | | | | | | | | | | | | | | The error generated by the compiler was: no matching function for call to 'maxi' RealScalar threshold = numext::maxi(tol*tol*rhsNorm2,considerAsZero); The important part in the following notes was: candidate template ignored: deduced conflicting types for parameter 'T'" ('codi::Multiply11<...>' vs. 'codi::ActiveReal<...>') EIGEN_ALWAYS_INLINE T maxi(const T& x, const T& y) I am using CoDiPack to provide the RealScalar type.
