How to fix loop which over the determined index ?

Hi guys, im trying to do looping ii 1:900 but why when u run it, it was never-ending loop. After reach 900, it will continue to 901 but using model with i = 1 (start again from beginning).

Here are my code:

%% clean-up the workspace & command window
clc;
clear;
clc;
tic;

% this allows for a connection to a version of ETABS other than the latest installation
% otherwise the latest installed version of ETABS will be launched

% if the above flag is set to true, specify the path to ETABS below

    SapObject = helper.GetObject('CSI.SAP2000.API.SapObject');

        % create an instance of the ETABS object from the specified path
        SapObject = helper.CreateObject(ProgramPath);

end
helper = 0;

"Hi guys, im trying to do looping ii 1:900 but why when u run it, it was never-ending loop."

I already told you the reason why, in my comment to your previous question:

https://www.mathworks.com/matlabcentral/answers/2118221-how-to-show-live-return-of-variable-in-command-windows-while-running-a-looping#comment_3159771

Get rid of the outermost loop. Your outermost loop basically duplicates all of the other loops:

• the outermost loop iterates 900 times,
• within that you have lots of nested loops, which in total iterate 900 times,
• so your code will perform 900*900 iterations in total.

GET RID OF THE OUTERMOST LOOP.

this one i dont understand may you give me the code directly based on my script?

S(1).name = "Model"
S(1).char = "";
S(1).vals = 2:2;
S(2).name = "ENDT";
S(2).char = "A";
S(2).vals = 1:5;
..

"this one i dont understand may you give me the code directly based on my script?"

It is recommended to avoid meta-data in variable names, e.g. if you used e.g. the non-scalar structure as shown or similar approach then your code can be written in a more generalised way and likely without those deeply nested loops.

But that is just a recommended improvement.

To fix the bug you asked about in this thread, get rid of the outermost loop. That is all.
