You should use autogk.bas unit, which requires 16 other units: ap, tsort, hblas, reflections, creflections, sblas, ablasf, ablas, ortfac, blas, rotations, hsschur, evd, gammafunc, gq, gkq. Use it as follows: Code: Dim State As AutoGKState
Dim V As Double Dim Rep As AutoGKReport ' ' f(x) = 3*x^2 + x/2 ' Exact answer is 2*pi ' Call AutoGKSmooth(3, 5, State) Do While AutoGKIteration(State) State.F = 3*State.X*State.X + 0.5*State.X Loop Call AutoGKResults(State, V, Rep) ' Now V contains result
