Variable Documentation

const unsigned int ActualPacketAccessBit = 0x0

Definition at line 102 of file Constants.h.

const int Dynamic = -1

This value means that a quantity is not known at compile-time, and that instead the value is stored in some runtime variable.

Changing the value of Dynamic breaks the ABI, as Dynamic is often used as a template parameter for Matrix.

Definition at line 34 of file Constants.h.

const unsigned int HereditaryBits

Initial value:

 RowMajorBit
                                  | EvalBeforeNestingBit
                                  | EvalBeforeAssigningBit

Definition at line 160 of file Constants.h.

const int Infinity = -1

This value means +Infinity; it is currently used only as the p parameter to MatrixBase::lpNorm<int>(). The value Infinity there means the L-infinity norm.

Definition at line 39 of file Constants.h.

const unsigned int NestByRefBit = 0x100
