Hi everybody,


I wrote a script using:

scalarSquareMatrix Kappa( DIM ,Zero);

and I access to the element writing Kappa[i][j];


now I need a sparse matrix, because I'm increasing the size of this matrix.


Can I just change the "declaration"? Or do I need to rewrite all the script in a different way?


I'm looking for something like sparse matrix Kappa(DIM)

https://es.mathworks.com/help/matlab/ref/sparse.html

I tried with:
LduMatrix<scalar,scalar,scalar> Kappa(DIM), but it doesn't work.


At the end I solve a system like that:

scalarField RHS(size, 0);

LUscalarMatrix LU(Kappa);

scalarField UU(LU.solve(RHS));

Thanks for the help in advance!
