Statistical Mode

Finds the "mode" (most occuring element) in a 1D number REAL array

Description

Mode function for MATLAB 6.1 or above

Syntax: [mode,modal,times] = ms_modal(x);
where :
x is the 1-D input array consisting of REAL numbers, in either row or columnar form modal is the output which consists of the numbers appearing in array x. It has each number once only. This is not sorted.

times is the array which records how many times each corresponding number in modal occurs

Example:
        x = [1 2 3 4 1 1 2]
        [mode,modal,times] = ms_modal(x);
 gives:
 mode = 1
 modal =
 
      1 2 3 4 0 0
 
 
 times =
 
      3 2 1 1 0 0

*************************************

LIMITATION: ONLY OUTPUTS 1 ELEMENT AS THE MODE.

Let me know if you run into problems!

• MATLAB release: MATLAB 6.1 (R12.1)

Just a little correction: This function does not find the "mode" in a character array, although it something it can address with some little additional programming.

Limitation: Displays a single mode only even if other numbers occur the same number of times.

Apparently doesnt work if negative numbers are present...
