I am using two around 9 million sparse matrix to do a sample calculation. MATLAB is giving me this warning. How should I correct this?
>> displacement = K_matrix_sys\F_matrix;
Warning: Matrix is close to singular or badly scaled. Results may be inaccurate. RCOND = 1.326659e-16.
K_matrix_sys is sysmetric matrix, F_matrix is same size array. How should I fix this? Where should I start to check with?

You don't have to correct any thing.
The matrix is close to singular (the determinant close to zero)
Matlab indicate that Results may be inaccurate.
The problem is in the matrix itself
