Hi
I'm new to Eigen.

Apologies for a basic question. I'm trying to work out how I can simply concatenate matrices as per Matlab:

A = [ 1 2 3,
7 8 9,
13 14 15]


B = [4 5 6,
10 11 12,
16 17 18];

C = [A B];

ans =

1 2 3 4 5 6
7 8 9 10 11 12
13 14 15 16 17 18


I know I can copy a matrix A to C, and resize C, and then copy values across, but is there any way to do this in one to two lines of code?

Thanks,
Peter

2 lines:

C.resize(A.rows(),A.cols()+B.cols());
C << A, B;

Works perfectly, many thanks!
