mikera.matrixx.solve.impl.CholeskyLDUSolver.solve()

Using the decomposition, finds the value of 'X' in the linear equation below:
A*x = b
where A has dimension of n by n, x and b are n by m dimension.

*Note* that 'b' and 'x' can be the same matrix instance.
@param B A matrix that is n by m. Not modified. @param X An n by m matrix where the solution is writen to. Modified.

    Matrix x;


        CholeskyLDUSolver solver = new CholeskyLDUSolver();
        assertTrue(solver.setA(A));
        Matrix A_inv_result = solver.invert().toMatrix();
        x = solver.solve(b).toMatrix();


        double[][] data_A_inv_expected = {{1.453515, -0.199546, -0.013605}, 
                          {-0.199546, 0.167800, -0.034014}, 
                          {-0.013605, -0.034014, 0.020408}};
        Matrix A_inv_expected = Matrix.create(data_A_inv_expected);
