What is the user-defined function in MATLAB?
A user-defined function in MATLAB is a piece of code or a program that we can create and use later as any other in-built function. All we need to do is save our code as a text file and ensuring that the name of our function is the same as the file we are saving it in.How do you add a user-defined function in MATLAB?

1Step 1: How to Open a Function File. Open the MATLAB software on your computer. 2Step 2: Get to Know the MATLAB Interface. 3Step 3: Writing Your Function in a Script File. 4Step 4: How to Save and Run the User-defined Functions. 5Step 5: Congratulation.What are the 4 user-defined functions?
A user-defined function can be a scalar function, which returns a single value each time it is called; an aggregate function, which is passed a set of like values and returns a single value for the set; a row function, which returns one row; or a table function, which returns a table.- y = pdf( name , x , A ) returns the probability density function (pdf) for the one-parameter distribution family specified by name and the distribution parameter A , evaluated at the values in x .
