0a18eecab3 bug #100: add support for explicit scalar to Array conversion (as enable implicit conversion is much more tricky) 2014-09-19 13:25:28 +02:00
Jitse Niesen
de150b1e14 Add documentation and very simple test for array atan(), part 2 
(files I forget in the previous commit).

36052c4911 Added comparisons scalar to array (previously only the array to scalar was possible) (Fixes bug #147) 
Extended the unit test for that

a76fbbf397 Fix bug #314: 
- remove most of the metaprogramming kung fu in MathFunctions.h (only keep functions that differs from the std)
- remove the overloads for array expression that were in the std namespace

039408cd66 added functions to allow for cwise min/max operations with scalar argument (bug #400). 
added function for array.min(), array.max(), matrix.cwiseMin(), matrix.cwiseMax().

The matrix.cwiseMin/Max functions required the definition of the ConstantReturnType typedef.
However, it wasn't defined until after MatrixCwiseBinaryOps was included in Eigen/src/SparseCore/SparseMatrixBase.h,
so I moved those includes after the definition of the typedefs.

tests for both the regular and scalar min/max functions were added as well

837db08cbd Add test for sqrt() on complex Arrays. 
From Gael's dashboard output of matrix_square_root test, I suspect the
test committed here may fail on old gcc.

83e3c4582f Improved the array unit test - internal::isApprox needs to use the same precision as VERIFY_IS_NOT_APPROX.

7bc8e3ac09 Initial fixes for bug #85. 
Renamed meta_{true|false} to {true|false}_type, meta_if to conditional, is_same_type to is_same, un{ref|pointer|const} to remove_{reference|pointer|const} and makeconst to add_const.
Changed boolean type 'ret' member to 'value'.
Changed 'ret' members refering to types to 'type'.
Adapted all code occurences.

5d63d2cc4b * kill the retval typedefs, instead introduce ei_xxx_retval which does the job automatically in 99% cases and can be specialized 
* add real/imag/abs2 global functions for Array
* document ei_global_math_functions_filtering_base
* improve unit tests

e277586958 Complete rework of global math functions and NumTraits. 
* Now completely generic so all standard integer types (like char...) are supported.
** add unit test for that (integer_types).
* NumTraits does no longer inherit numeric_limits
* All math functions are now templated
* Better guard (static asserts) against using certain math functions on integer types.

e3d890bc5a Another big refactoring change: 
* add a new Eigen2Support module including Cwise, Flagged, and some other deprecated stuff
* add a few cwiseXxx functions
* adapt a few modules to use cwiseXxx instead of the .cwise() prefix

2840ac7e94 big huge changes, so i dont remember everything. 
* renaming, e.g. LU ---> FullPivLU
* split tests framework: more robust, e.g. dont generate empty tests if a number is skipped
* make all remaining tests use that splitting, as needed.
* Fix 4x4 inversion (see stable branch)
* Transform::inverse() and geo_transform test : adapt to new inverse() API, it was also trying to instantiate inverse() for 3x4 matrices.
* CMakeLists: more robust regexp to parse the version number
* misc fixes in unit tests

e14aa8c8aa Add coeff-wise comparisons to scalar operators. You can now write: 
mat.cwise() < 2
instead of:
   mat.cwise() < MatrixType::Constant(mat.rows(), mat.cols(), 2)
 2008-09-03 17:56:06 +00:00

59dc1da5bf Add a Select expression in the Array module which mimics a coeff-wise ?: operator. 
Example:
  mat = (mat.cwise().abs().cwise() < Ones()).select(0,mat);
replaces all small values by 0. (the scalar version is "s = abs(s)<1 ? 0 : s")

46fe7a3d9e if EIGEN_NICE_RANDOM is defined, the random functions will return numbers with 
few bits left of the comma and for floating-point types will never return zero.
This replaces the custom functions in test/main.h, so one does not anymore need
to think about that when writing tests.

c10f069b6b * Merge Extract and Part to the Part expression. 
Renamed "MatrixBase::extract() const" to "MatrixBase::part() const"
* Renamed static functions identity, zero, ones, random with an upper case
  first letter: Identity, Zero, Ones and Random.

05ad083467 Added MatrixBase::Unit*() static function to easily create unit/basis vectors. 
Removed EulerAngles, addes typdefs for Quaternion and AngleAxis,
and added automatic conversions from Quaternion/AngleAxis to Matrix3 such that:
 Matrix3f m = AngleAxisf(0.2,Vector3f::UnitX) * AngleAxisf(0.2,Vector3f::UnitY);
just works.
