Macro Definition Documentation

#define EIGEN_ARCH_DEFAULT_NUMBER_OF_REGISTERS

Defines the default number of registers available for that architecture. Currently it must be 8 or 16. Other values will fail.

#define EIGEN_CACHEFRIENDLY_PRODUCT_THRESHOLD

Defines the threshold between a "small" and a "large" matrix. This threshold is mainly used to select the proper product implementation.

#define EIGEN_TUNE_TRIANGULAR_PANEL_WIDTH

Defines the maximal width of the blocks used in the triangular product and solver for vectors (level 2 blas xTRMV and xTRSV). The default is 8.

#define EIGEN_UNROLLING_LIMIT

Defines the maximal loop size to enable meta unrolling of loops. Note that the value here is expressed in Eigen's own notion of "number of FLOPS", it does not correspond to the number of iterations or the number of instructions
