How to iterate through genfit parameters?

[Cornel]

Hello,

These examples are for each particular i:

But how to iterate through all values of i:

[Werner_E · Accepted solution]

Maybe that way

If that ratio is all that is of interest, you should modify the function beta.in_out accordingly so that it only returns that ratio.

Another way could be to turn each of the "genfit" calls into a separate function of the index:

[Cornel]

Yes, the second variant.

But look:

How to extract each i from the above two vectors?

[Werner_E]

I don't understand what you are looking for!?

The values you calculate singly for i=4 and i=10 seem to match perfectly with the appropriate values in the calculated vectors.

I see no problem or error here.

Or could it be that you stumble across this age-old problem??

If that's the case you may have a second look at how I defined the vector(!) "ratios" in my answer above!!

Look:
I want to extract from the 20log() vector each i value:

Because look:

Compare the 2 vectors and you will see that they are different

[Cornel]

So,

And from this vector I want to extract only the value corresponding to i=1:

Then if i=2:

And to put these values for each i into another vector:

?? See my edited answer above. Assign the 20log() expression to a variable so its a vector and access the appropriate element.

Or furmulate that expression as a function of i if thats more appropriate.

Not sure what you mean!? You use two different values for i. Of course you get two different vectors.

On the other hand I don't understand why you get vector like results anyway if you use a single scalar for i ??????

You should get something like

I used the sheet you posted last. The values are different so I guess you are using different data in your picture

[Cornel]

I was expecting something like this to be in 20log() vector:

And so on...

I used the data and sheet you posted last and I have no idea where you would get these values from!?

When I do it, I get

and this perfectly corresponds with the first two values in the full vector we crated

These are the mathcad file prime 9 and excel with data used:

Something is not updated accordingly...

Oooops!!

I'm very sorry but it looks like I mistakenly edited your post instead of replying to it!

So you can see my answer in the reply YOU posted -> https://community.ptc.com/t5/Mathcad/How-to-iterate-through-genfit-parameters/m-p/945065/highlight/true#M211414
Nevertheless, the question remains as to where the values in your pictures come from, which I cannot understand with your Excel data and the last prime sheet you posted.
