Re: [eigen] Large matrix problem

[ Thread Index | Date Index | More Archives ]


Indeed, Eigen 2 uses 32bit indices (well, assuming that sizeof(int)==4) so you just can't do that in Eigen2.

But Eigen3 uses indices the size of a pointer, which means that with Eigen3, on a 64bit platform, you can have arbitrarily big matrices.

I encourage you to try Eigen3, i.e. the development branch in hg. It should definitely fix your problem.

14000*14000*22 > 256^4, so it may be a problem with a 32 Bit value in a loop. Maybe you should split the Matrix.
