MATLAB is a high-performance language that is used for matrix manipulation, performing technical computations, graph plottings, etc. It stands for Matrix Laboratory.
Functions:
The function is a set of statements or commands, which take input/s as parameters and return output. We write functions to use it again and again in the program i.e. it makes a block of code reusable. It makes it easier to find errors and also reduces code redundancy.
Types of Function:
Library Functions: In MATLAB Software, there are some inbuilt functions, which take input as arguments and return output. E.g. log(x), sqrt(x), line space(a,b,n), etc.
User-Defined Functions: In MATLAB, we also create functions by writing Matlab commands in files that take input/s as argument/s and then return the output. Also, save the function file using the name of the function itself.
Steps to Create a Function File in MATLAB:
Step 1: Create a file and write commands using the function keyword.
Step 2: Save the function file with the same name as the function. Here I have saved the file with the name solve.m.
Step 3: Use the function in Command Video by providing suitable argument/s.
Now we see creating a function and saving it in MATLAB.
Example 1:
Using the function to be called in Command Window.
