Hey acer, 

It didn't work with Digits:=20:  

It actually removed the "minus" from the 0, so it only said "0." 

And now, even though I deleted "Digits:=20:", it still gives me "0." rather than "-0." from before. How can I change it back?

Hey Carl, thanks for your help as well! 

I wrote the interface command and it gave me -1, so I don't know what could be the problem then.


I don't know what this custom initialization file could be :/ 

But it's interesting that you get the right result without any problems! 


Sorry! I have attached the data now :)



By "read the mean-value,mu" I just mean reading the number of the mu-symbol."  

How do I increase Digits? I haven't used that before. Where can I find it in my residualQQplot? 

@Preben Alsholm 

Alright, thanks for the help! :)

@Preben Alsholm 

I edited my original post, where you can download it at the bottom of the post :) 

I have uploaded in this message as well. Can you download it? :)

@Preben Alsholm 

Alright, I think I understand it now. I'll try it. Thank you for all your help! 

@Preben Alsholm 

Thank you both very much for your answers! I'll try to make it work that way instead of using "linjeelementer" just. 

Just a quick question: What does these commands mean and do? Do I have to write all this every time to plot the slope field with a line showing the movement of the line elements in it? 

plot(eval(rhs(SOL),z=z1),t=0..800); # Constant (roughly)
