Thank you, Christian

@dharr 

Thank you so much

Hi Tomleslie here is the link to my code: NNMMM.mw

@dharr 

Thank you 

@tomleslie 

Thank you for the explanation

@tomleslie 

I'm kind of confused. Please in mydata, which column corresponds to xi =0 and xi =0.1. I want to differentiate them for plotting purposes.

@tomleslie

 Thank you very much. I really appreciate your help

@tomleslie 

Maybe I attached the wrong file. In the file: Case1_Revised_080922.mw the line has: 

ExcelTools:-Export(op([1, 1], plots:-display( convert( ans1[12..14,3], list))));

You may be wondering why am I doing this. While I wanted to export my data from maple to Matlab and compare it with my result in Matlab. I tried to export it as a Matlab script but couldn't work. So I had to use ExcelTools. So, I exported only my plots which are okay for only one value of xi. But for several values of xi, it couldn't work. If there are other alternatives, I need your suggestion.

@Carl Love

Thank you

Unfortunately it didn't work on my maple version. I recieved this error message:

Error, invalid input: rand expects its 1st argument, r, to be of type {posint, integer .. integer}, but received 0. .. 1.
Error, invalid input: no implementation of Color matches the arguments in call, 'Color:-ModuleApply([r(), r(), r()])'

@dharr 

For instance how do I plot a function with singularities such that the asymptotes don't appear

f(x,y) = y/(x+1) + 1/(y^2-y) 

@dharr 

Unfortunely, plot3d don't accept discont=true as an argument.

@dharr 

Thanks. I actually use this as an instance.
