Hi Michael, Array returns a list of functions. Therefore, when you say G=Array[a,..] and a[i] already has a value, the functions a[i] will be evaluated and you end up with a list of numbers, not functions. To prevent this, Clear a before using it. hope this helps, Daniel Michael Mandelberg wrote: > I am running v. 6.0.3.0 > > I am having some weirdness where I will do something like: > > G=Array[f,100]; > For[i=1, i<=100, i++, > f[i] = some calculation] > > Then I will look at the result: > > ListLinePlot[G] > > The strange thing is, if I rerun this, but change 'some calculation' > to 'some other calculation', then rerun the plot, the plot stays the > same.
