@DSkoog , @tomleslie, @nm

Thank you all for the kind response, I'll try your tips.

@tomleslie and DSkoog,

Tx for the kind reply. I also thought to use the DataFrame tool, but as a Maple newbie I could not decide whether this is a good idea, or not. Whether TimeSeries, DataFrames of Tables, etc. does not matter, the solution itself is the most important.

One can learn a lot from your codes,

tx once again,

best regards

@a_simsim 

I think I found the solution myself:

1. Append a new row or column,

2. Reorder rows and columns as appropriate.

:-)

@Kitonum 

Dear Kitonum,

Tx very much, I should have realized. Does this go also reversed, i.e. inserting rows and columns into arbitrary locations?

Tx once again,

best regards

@acer 

Dear acer,

Thank you very much for the advice. l'm still a newbie in Maple, so there is still a lot to learn and practice.

best regards,

Andras

@acer 

Dear acer,

Thank you very much for the quick answer. Wow, the chart looks, and behaves exactly the way I wanted. I would have never figure it out, tx once again for the kind help.

best regards

Andras

@Preben Alsholm 

Dear Preben, and others,

Thank you very much for your kind efforts, it will help me a lot.

@Carl: 12.319 was tabulated in a book, in a look up table, I got it from there. I guess the solution there was obtained with a similar method Preben listed above, but it was not specified explicitly how. Preben gets pretty close to it.

Tx once again,

@Preben Alsholm 

Absolutely right, sorry, I should have known. Works perfect, thank you for the help,

cheers

@tomleslie 

Dear Tom,

By more sophisticated I mean the following: I have measured values (a time series) which I would like to match with a mathematical model. This however is not trivial, it has some nonlinear equations, nonlinear functions, etc. which have to be solved numerically, and cannot be specified as a single line of code, but rather as a procedure. This simple nonlinear curve fit experiment above was intended only to explore Maple's capabilities on how to do the match, so now I can go for the more complicated problem. With the kind helps listed above I think I can master it now.

Tx once again,

best regards

Andras

@Carl Love 

Dear Carl,

Wow, thank you so much, this is very valuable help for me.

best regards

Andras

@Kitonum 

One more elegant solution, thank you very much :-))

@tomleslie 

Dear Tom,

Works perfect, tank you very much :-)) May I have one more question? What if I have a more sophisticated procedure instead of Model, which is only one line? How should I proceed then? I guess I have to set up a procedure for the more sophisticated model, right?

Tx in advance,

best regards

Andras

@Carl Love 

Dear Carl,

Thank you for the kind help. I got the numbers actually from Excel, there might be a small discrepancy between Excel and Maple. I'll check out the Finance package more in detail.

Tx once again,

best regards

Andras

@acer 

Dear acrer,

Tx for your 2nd solution, now I have 2.

@Preben Alsholm 

Dear Preben,

Works perfect, great help, I was struggling with it for a while.

Tx a lot, best regards
