    I think you need to define better what you actually want.

    What sort of coefficients - real or complex?

    What size of equations - 10x10 or 10,000,000 x 10,000,000?

    Any special properties of the left hand side matrix - general? symmetric? banded? positive definite? Hermitian? tridiagonal? etc etc.... there are different (efficient) algorithms for all of them.

    The sort of coefficients is real number and the size is n by n ( general method ) n*n .

    thank you ever so much
