Array of pointers to Eigen Matrices

Question

I am using MatrixXd matrices from Eigen on my code, and at a certain point I need a 3D one. Since Eigen does not have tridimensional matrix types, as it is optimized just for li

Answer 1

Just use operator()(int,int)

CVM[k].operator()(i,j) = 47;

or

CVM[k](i,j) = 47;

or

Eigen::MatrixXd* b = &CVM[k];
b->operator()(i,j) = 47;

Here k is the matrix, i is the row, and j is the column.
