How to find the closest value to the average in an array?

I get a different one dimentional array for different inputs. Now, I want to take the average value of the array, and find the value that is closest to it.

For example if the array output is like this:

a = [1,2,3,4,5,6,7]

Then average will be 4.14, which is closest to 4.

So, the answer should be 4.

How can I do it?

Answer 1

[KSSV]

a = [1,2,3,4,5,6,7] ;
[val,idx] = min(abs(a-mean(a)));
a(idx)

ans = 4

Answer 2

[KSSV]

a = [1,2,3,4,5,6,7] ;
idx = knnsearch(a',mean(a)) ;
a(idx)

ans = 4

Then average will be 4.14, which is closest to 4.

actually average is 4. you can try this:

a=[1,2,3,4,6,6];
average=mean(a)

average = 3.6667

[~,~,idx]=unique(round(abs(a-average)));
nearest_value=a(idx==1)

nearest_value = 4
