Here we discuss the examples of Matlab user defined function along with the inputs and outputs. This is a guide to Matlab user defined function. The name of these text files must be the same as the name of our function.These user defined functions are stored as text files and can be called whenever required.We can create user defined functions in MATLAB to use them as built-in functions.Save the file by the name compute_volumeĪs we can see in the output, our user defined function has given us the volume of a sphere with a radius of 4, i.e.Write the logic to compute the volume of a sphere.We will name our function as compute_volume, and so our file name will also be compute_volume. In this example, we will create a user defined function to calculate the volume of a sphere. Next, we will call this function from a new MATLAB command windowĪs we can see in the output, our user-defined function has given us the area of a circle with a radius of 5, i.e. Write the logic to compute the area of a circle.classdef methodDemo properties Property1 end methods function prod propMultiply (obj,inputArg) prod obj.Property1inputArg end function quotient propDivide (obj,inputArg) quotient obj.Property1/inputArg end end end. We will name our function as compute_area, and so our file name will also be compute_area. The methods calculate the product and quotient of the value of the class property, Property1, and the input argument. In this example, we will create a user-defined function to calculate the area of a circle. (Please note that the name of the file is the same as the name of the user-defined function)Īs we can see in the output, our user-defined function has given us the factorial of 6, i.e. This is how our input and output will look like in MATLAB: Next, we will call this function from a new MATLAB window Call this function in the new Matlab window using the name and passing the argument.Save the file by the name compute_factorial.Write the logic to compute the factorial of a number.Initialize the function compute_factorial.We will name our function as compute_factorial, and so our file name will also be compute_factorial. In this example, we will create a user-defined function to calculate the factorial of a number. Let us now understand the code to create a user-defined function in MATLAB Example #1 Please note that the func_name is required, whereas there can be zero input & output arguments.Īlso, the name of the function defined by us and the name of the file we save it in must be the same.
