On analysing the code snippet provided, I understand that this code is a simple implementation of the Euler method.
In the following line of code we are populating the vector ‘x’
x = (x0:h:xn);
Here, 'x0' represents the initial value, 'xn' denotes the final value, and 'h' is the step size used to populate the array. 'x(1)' will be equal to 'x0', with every subsequent element increasing by the step size 'h' until the value in 'x' reaches or exceeds 'xn'.
This is also elaborated on in the following MATLAB Answer thread: https://www.mathworks.com/matlabcentral/answers/151486-creating-an-array-of-given-size-and-increment
The ‘for’ statement iterates from the second element of the vector ‘x’ to the last one. This is because the first value of ‘y’ is already set as the initial condition ‘y0’. Please note that for solving an ODE using the Euler method, given an initial condition and a function 'f' defined as a function handle, you must remember to replace the example function 'f' with your specific function that defines the ODE you wish to solve.
Hope this helps!
