249dc4f482current state of the mess. One line fails in the tests, and useless copies are made when evaluating nested expressions. Changes: - kill LazyBit, introduce EvalBeforeNestingBit and EvalBeforeAssigningBit - product and random don't evaluate immediately anymore - eval() always evaluates - change the value of Dynamic to some large positive value, in preparation of future simplifications

b8900d0b80More clever evaluation of arguments: now it occurs in earlier, in operator*, before the Product<> type is constructed. This resets template depth on each intermediate evaluation, and gives simpler code. Introducing ei_eval_if_expensive<Derived, n> which evaluates Derived if it's worth it given that each of its coeffs will be accessed n times. Operator* uses this with adequate values of n to evaluate args exactly when needed.

c9b0dcd733look at that subtle difference in Product.h... the cacheOptimal is only good for large enough matrices. When taking a block in a fixed-size (hence small) matrix, the SizeAtCompileTime is Dynamic hence that's not a good indicator. This example shows that the good indicator is MaxSizeAtCompileTime. Result: +10% speed in echelon.cpp

a994e51c96* add Gael copyright lines on 2 more files * macro renaming: EIGEN_NDEBUG becomes EIGEN_NO_DEBUG as this is much better (and similar to Qt) and EIGEN_CUSTOM_ASSERT becomes EIGEN_USE_CUSTOM_ASSERT * protect Core header by a EIGEN_CORE_H
Benoit Jacob
2008-03-26 09:13:11 +0000
729618c945* #define EIGEN_NDEBUG now also disables asserts. Useful to disable eigen's asserts without disabling one's own program's asserts. Notice that Eigen code should now use ei_assert() instead of assert(). * Remove findBiggestCoeff() as it's now almost redundant. * Improve echelon.cpp: inner for loop replaced by xprs. * remove useless "(*this)." here and there. I think they were first introduced by automatic search&replace. * fix compilation in Visitor.h (issue triggered by echelon.cpp) * improve comment on swap().

0ef1efdbdb* cleanup: in public api docs, don't put \sa links to \internal things. (the global funcs in MathFunctions.h and Fuzzy.h don't count as internal). * Mainpage.dox. Add a few prospective Eigen users; change the recommended -finline-limit from 10000 to 1000. The reason is: it could be harmful to have a too big value here, couldn't it? (e.g. exceedingly large executables, cache misses). Looking at gcc, a value of 900 would exactly mean "determine the inlining of all functions as if they were marked with 'inline' keyword". So a value of 1000 seems a reasonable round number. In the benchmark that motivated this (TestEigenSolvers) a value of 400 is enough on my system.

fb3438e609- expand MathFunctions.h to provide more functions, like exp, log... - add cwiseExp(), cwiseLog()... --> for example, doing a gamma-correction on a bitmap image stored as an array of floats is a simple matter of: Eigen::Map<VectorXf> m = VectorXf::map(bitmap,size); m = m.cwisePow(gamma); - apidoc improvements, reorganization of the \name's - remove obsolete examples - remove EIGEN_ALWAYS_INLINE on lazyProduct(), it seems useless.
