Hello all,
I need your help for my class project. I need to add a for loop to my code and delete last row (time and displacement vectors) of the txt file for each iteration.Also, for each iteration I want to store my parameters and get plot. My aim is checking the time, is it long or enough? I've tried some codes and read previous questions but I couldn't fix my code.I'm really got stuck. If you're able to help,I'd be appreciate. Thanks

What does "delete last row of text file" mean? Do you really want to modifiy the file?
What does this mean: "for each iteration I want to store my parameters and get plot"? A plot of what? I do not understand this also: "checking the time, is it long or enough"? How is "enough" defined?
What is the problem with your code?
By the way, source code looks like 1980 with all variables in UPPERCASE.

- List path to all text files. See dir.
- Read in the text file. See readtable, readmatrix, readcell,readtimetable.
- Eliminate the last row using indexing. T(end,:)=[];
- To store values within a loop, see preallocation, and use indexing.
If you get stuck, circle back in for another comment and show us what you've got.

Are you asking how to design the objective function for lsqnonlin? There are examples in the documentation.
And here's info on passing additional values
Or are you asking how to preallocate a loop variable for storing the model outputs?
