A = [ 1 5 8 ]
then

Really found a lot of trouble to find the solution.
But could not find how someone could solve it just using a size of 7.
good one
What matlab functions are useful for this ? (I did it with a loop)
Good problem if you don't use repelem
I think the test should also check for column vectors and any vector with special variables Inf and NaN
Nice problem without using kron function
B = [ A A];
Is a valid answer! Your problem statement says nothing about the element in vector b being in order. Test 2 is correct for only one case.
Use repelem inbuilt function
