% prepare environment and generate aircraft trajectory clear all; close all; clc; data = zeros(400,6);
% x, y and z coordinates data(:,1) = 0; data(:,2) = .5:.5:200; data(:,3) = 500;
% pitch, yaw and roll angle values data(:,4) = 0; data(:,5) = 0; data(21:380,6) = (1:1:360)/57.3;
% prepare aircraft simulation model new_object('aircraft.mat',data,... 'model','f-16.mat', 'edge',[.1 .1 .1],'face',[.1 .1 .1],... 'path','on','pathcolor', [.89 .0 .27],'pathwidth',1,'scale',1);
% generate the scene and save the result as gif file flypath('aircraft.mat',... 'animate','on','step',3,... 'font','Georgia','fontsize',10,... 'view',[35 45],'window',[700 700],... 'output','aileron_roll.gif',... 'xlim',[-20 20],'ylim',[0 200], 'zlim',[480 520]); The image shows the diagram on a z, x & y axis. I want to change coordinates as z in place of x and y in place of z and x in place of y.

I understand that you want to change the axis of your 'data' as z in place of x and y in place of z and x in place of y before adding to the 'new_object_model' which is futher used in the 'flypath' function.
You can change the coordinate axis by creating a tranformed_data array as mentioned below:
% Transform coordinates: swap x -> y, y -> z, z -> x
transformed_data = zeros(size(data));
transformed_data(:,1) = data(:,3);
transformed_data(:,2) = data(:,1);
transformed_data(:,3) = data(:,2);
This 'transformed_data' array can be passed in place of 'data' to custom functions like 'new_object' and 'flypath' mentioned in your code to change the axis of simulation as mentioned by you.
You can refer to the following documentations to know more about MATLAB functions and Simulink blocks for achieving the desired result:
'Aerospace Coordinate Systems': https://www.mathworks.com/help/releases/R2024a/aeroblks/about-aerospace-coordinate-systems.html
'Simulion 3D Aircraft': https://www.mathworks.com/help/releases/R2024a/aeroblks/simulation3daircraft.html?searchHighlight=aircraft%20simulation&s_tid=doc_srchtitle
Hope this helps! Thanks.
