extract a row from an iteration - I need help writing this iteration - Сообщения
#1 Опубликовано: 17.05.2023 11:23:59
I am learning how to use Smath Studio, I want to write an iteration where an increment of 0.5 is added to two declared variables "a" and "b" which are replaced in a formula and it gives me a final value "X" and the condition is that the iteration stops when the final value is equal to or less than a declared value "Y" to finally extract from the iteration array the row with the three values that meet this condition: [a b X]
I appreciate your help in advance, I am willing to donate

Show your departure work, to be more helpful.
Cheers ... Jean.
This is the structure that I have been writing to iterate but I need to extract the row of interest, which in this example has to be less than or equal to sigma_adm_suelo, this row is the last

I already resolved it

Greetings,
You may want to consider the use of a for loop instead of a while statement:
Copy and Paste the following into your worksheet:

The result I am looking for is that it meets the initial condition, how would I stop at the iteration that meets this condition, to be able to do it using the "for" command that you suggested and not the 10 iterations that I declare for "i"

Greetings,
The 'i < 10' statement would be replaced with your criteria (ie., ≤ σ.adm_suelo). Regardless, the largest issue you have is with regards to how SMath programs; you need to follow the 'rules' of setting up programming functions within a line() group, where the last item is the value returned as a result.
Copy and paste the following into your worksheet:
The matrix produced by C.Summary should be what you are after (I simplified the equ by removing Maxima() function calls)

Maxima is not popular in the Smath Community users.
Don't even recall a single of those decoration gyzmas.

I have a problem, the power went out and now my file does not open. What can I do, does anyone know how to restore it?

Hello Orlando,
I'm sorry but the file is not recoverable (is filled with null characters).

Code the while loop from reconstruction.

Hello, I have already made progress with a new file, I used the "for" command and after extracting the first matrix with the values that meet the condition, I made the next iteration with another formula compare the first two columns and extract the matches next to the third column that has a different result, thanks for the help to all of you, I will continue posting new concerns and I will make my donation to smath studio
