[eigen] Cost of a map operation

[ Thread Index | Date Index | More lists.tuxfamily.org/eigen Archives ]

What is the cost of this map operation?

AddressVector_t AddressVector = Map<AddressVector_t,ForceAligned>(address)

where AddressVector_t itself is a typedef for

typedef Matrix<int,cordNum,1> AddressVector_t;

cordNum is a compile time constant.

This map operation occurs in inner loop of my application, so I want
to know, how costly is it gonna be? I mean with what use in mind was
it written for?
