MATLAB Mode Function in MATLAB: Explained by Ivan

Click For Summary
The mode function in MATLAB is used to identify the most frequently occurring value in a dataset. In the provided example matrix, the mode function can be applied to find that the value 3 appears most frequently, totaling four occurrences. To use the mode function in a .m file, the matrix should be reshaped into a single vector if the goal is to find the mode across the entire matrix. The MATLAB documentation offers examples on how to implement this effectively. Understanding these steps allows for accurate usage of the mode function in various contexts.

Hi, I am a bit confusing on the mode function in MATLAB. I have look throught some books and say we can use mode function to find "the most show up value" and "show up how many times". For example :
r =

2 2 3
3 3 3
4 2 1

the most show up value is 3 and it shows up 4 times. The mode function will be mode(3,4)??How can i use it in .m file? Like i have "r" and now i want to use mode function to find the 3 and 4??Is there any example for that? coz lots of books just discrible what is mode function and didnt say how to use. Could anyone give me a hand on this?

Thanks
Ivan

In addition to what I said in your other thread, the online documentation has a great number of examples. For instance, for the mode command:

As per the link above, when you have a matrix, the mode command finds the most frequently-occurring (not 'showed-up') values in every column. If you wanted to find the most frequently-occurring value in the entire matrix, you need to turn the matrix into a single row or column vector using reshape:
