42af5870a4 Fix array unit test: isApprox(log(0),log(0)) is false, and summing up signed float value might result in very small values and thus large numerical errors 2013-02-23 22:58:14 +01:00

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.
Removed debug code from test_isApprox.

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

6347b1db5b remove sentence "Eigen itself is part of the KDE project."
it never made very precise sense. but now does it still make any?

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.
