Gael Guennebaud e23bf40dc2 Add unit test for LinSpaced and complex numbers. 2019-02-18 22:03:47 +01:00
Gael Guennebaud 48fe78c375 bug #1630: fix linspaced when requesting smaller packet size than default one. 2018-11-28 13:15:06 +01:00
Gael Guennebaud dff3a92d52 Remove usage of #if EIGEN_TEST_PART_XX in unit tests that does not require them (splitting can thus be avoided for them) 2018-07-17 15:52:58 +02:00
Gael Guennebaud 82f0ce2726 Get rid of EIGEN_TEST_FUNC, unit tests must now be declared with EIGEN_DECLARE_TEST(mytest) { /* code */ }. 
This provide several advantages:
- more flexibility in designing unit tests
- unit tests can be glued to speed up compilation
- unit tests are compiled with same predefined macros, which is a requirement for zapcc

Gael Guennebaud 9deee79922 bug #1457: add setUnit() methods for consistency. 2017-08-22 16:48:07 +02:00

Gael Guennebaud d06a48959a bug #1383: Fix regression from 3.2 with LinSpaced(n,0,n-1) with n==0. 2017-01-25 15:27:13 +01:00
Gael Guennebaud a07bb428df bug #1004: improve accuracy of LinSpaced for abs(low) >> abs(high). 2016-11-02 11:34:38 +01:00
Gael Guennebaud 58146be99b bug #1004: one more rewrite of LinSpaced for floating point numbers to guarantee both interpolation and monotonicity. 
This version simply does low+i*step plus a branch to return high if i==size-1.
Vectorization is accomplished with a branch and the help of pinsertlast.
Some quick benchmark revealed that the overhead is really marginal, even when filling small vectors.

Gael Guennebaud b027d7a8cf bug #1004: remove the inaccurate "sequential" path for LinSpaced, mark respective function as deprecated, and enforce strict interpolation of the higher range using a correction term. 
Now, even with floating point precision, both the 'low' and 'high' bounds are exactly reproduced at i=0 and i=size-1 respectively.

Gael Guennebaud 53c77061f0 bug #698: rewrite LinSpaced for integer scalar types to avoid overflow and guarantee an even spacing when possible. 
Otherwise, the "high" bound is implicitly lowered to the largest value allowing for an even distribution.
This changeset also disable vectorization for this integer path.

Gael Guennebaud e8e56c7642 Add unit test for overflow in LinSpaced 2016-10-24 15:43:51 +02:00
Gael Guennebaud b046a3f87d Workaround MSVC instantiation faillure of has_*ary_operator at the level of triats<Ref>::match so that the has_*ary_operator are really properly instantiated throughout the compilation unit. 2016-09-06 15:47:04 +02:00
Gael Guennebaud e13071dd13 Workaround a weird msvc 2012 compilation error. 2016-09-05 15:50:41 +02:00
Gael Guennebaud 218c37beb4 bug #1286: automatically detect the available prototypes of functors passed to CwiseNullaryExpr such that functors have only to implement the operators that matters among: 
operator()()
 operator()(i)
 operator()(i,j)
Linear access is also automatically detected based on the availability of operator()(i,j).

Gael Guennebaud fc202bab39 Index refactoring: StorageIndex must be used for storage only (and locally when it make sense). In all other cases use the global Index type. 2015-02-13 18:57:41 +01:00
