I am new to MATLAB programming and doesn't know how to use euler's method. please help me to understand that how should be execute while simulating a reaction.

Any line that starts with the word "function" must be stored in a .m file; in particular it must be stored in a function .m file or a classdef .m file, and not a script .m file. A function .m file is a file whose first non-comment is the word "function"; a classdef .m file is a file whose first non-comment is the word "classdef". Any .m file which does not start with "function" or "classdef" as the first non-comment is a "script" .m file, and functions cannot be saved in such files. functions cannot be entered at the command line in MATLAB and they cannot be in script files.
