MATLAB Help:
Create a 1 by 15 row vector of random integers between 1 and 20, then create one random integer between 5 and 15. Sort your vector according to how far away each of its elements is from that scalar integer, in the descending order of the absolute distance. Hint: use the sort() function.
example run:
The original vector is [12 10 1 7 4 16 7 11 4 13 6 14 14 15 10]]
Sorted by the distance away from 5,
from far to near, the new vector is [16 15 14 13 12 11 10 10 1 7 7 4 4 6]

Thank you for the help!
Explanation / Answer
The following code for the above problem can be either put in a separate matlab script file or can be run in command window line by line. Choose as per your convenience.
------------------------------------code to solve above problem is given below------------------------------------
%code starts here
%create a random distance variable whose value is between 5 and 15
dist = randi(10,1)+5
%create a vector of random integers between 1 and 20 of size 15
vec = randi(20, 1, 15)
%create another vector that stores distances from the random value generated above
%and sort this vector according to magnitude
vec2 = sort(vec-dist,2,'descend','ComparisonMethod','abs');
%the final sorted vector will be obtained by adding the distance value to each element of the sorted array
res = vec2 + dist
%above line prints the final vector sorted according to the distance from the random number
%code ends here
----------------------------------------------------end of solution code---------------------------------------------
Add or remove the semicolons at the end of the statements as you like according to whether you want the results to be printed or not.
