Examples of LowerSPDBandMatrix

no.uib.cipr.matrix.LowerSPDBandMatrix
Lower symmetrical positive definite banded matrix. It does not enforce this property (except for symmetry), and has the same storage layout as {@link no.uib.cipr.matrix.LowerSymmBandMatrix LowerSymmBandMatrix}.

Examples of no.uib.cipr.matrix.LowerSPDBandMatrix

        int n = Utilities.getInt(1, max);


        kl = Math.min(n, Utilities.getInt(bmax));
        ku = Math.min(n, Utilities.getInt(bmax));


        L = new LowerSPDBandMatrix(n, kl);
        Utilities.bandPopulate(L, kl, 0);
        Utilities.addDiagonal(L, 1);
        while (!Utilities.spd(L))
            Utilities.addDiagonal(L, 1);
