It should be saved with the name kf2.m and should look like this: function output = kf2 () output = 4; end More Answers (0) Know what function you want to graph. Anonymous functions are not stored to any program file. They can accept multiple inputs and return outputs. You must know what function you want to graph because you need to let MATLAB know what independent variables your function has before you write the function. Some examples of anonymous functions include:You should also remember that because Matlab functions are not too strict about number of parameters, overloading often depends on the number of sent input arguments or the number of requested output arguments. Therefore, someone may expect you to return both while the function returns only one parameter:When you use a mathematical function f(x) many times for different variables in a MATLAB program, a user-defined function is beneficial. A user-defined function is a separate file which is usable in any MATLAB program. A function file is a .m file, but different from a script file. When the input argument is a string array, the double function treats each element as the representation of a floating-point value. However, when the input is a character array, double instead converts each character to a number representing its Unicode® value. As an alternative, use the str2double function.str2double is suitable when the input argument might be a string array, character ...Often, it is difficult to know exactly what methods are available for an OpenSim class (e.g., Model, Muscle) and so using the API Documentation regularly will be useful.
