        spsolve ( _A, _B, _D_I_A_G___P_I_V_O_T, _P_E_R_M_V )

      DDeessccrriippttiioonn
        Solve solves a system of sparse linear equations:


          _A _* _X _= _B



        _A  is the coefficient matrix.

        _B  is the right hand side.

        _D_I_A_G___P_I_V_O_T
           specifies the diagonal-pivoting threshold.

        _P_E_R_M_V
           is the permutation vector.

        _X  is the solution vector/matrix.
