Expert in coding needed! matlab programming required

The statistic term, "mode", is the value that appears most often in a set of data. For example, the mode of this set of data, 2, 8, 5, 3, 7, 3, 4, 5, 3, is 3. A set of data can also be bi-modal or multi-model is two or more values occur for the same number of times. For example, the data set, 2, 5, 1, 4, 5, 2, 3, has two modes, 2 and 5. Write a script that generates a 1by20 vector containing random integers in the range [1-15], and then find the mode (or modes). Use the array traversing skills; do not use built-in functions such as sort () , max () , min () or mode ().

Explanation / Answer

findmodes.m

function [modes] = findmodes()

clc;

a = randi(15,1,20)
b = unique(a);
count = zeros(1,length(b));
for i = 1:length(b)
   count(i) = sum(a==b(i));
end
maxcount = count(1);
for i = 1:length(b)
   if count(i) > maxcount
       maxcount = count(i);
   end
end
temp_modes = (count == maxcount).*b;
modes = zeros;
num = 1;

for i = 1:length(temp_modes)
   if temp_modes(i) > 0
       modes(num) = temp_modes(i);
       num = num+1;
   end
end
modes

Output :

a =

Columns 1 through 15

    11     6     4     9    14     7     2     7     5     7    13     7     6     6     3

Columns 16 through 20

     4     2     7     4     5

modes =

     7
