Consider the following number system. Calculate the prime factorization for each number n, then represent the prime factors in a vector like so:
13 11 7 5 3 2 --------------- 2: 1 3: 1 0 4: 2 5: 1 0 0 6: 1 1 12: 1 2 14: 1 0 0 1 18: 2 1 26: 1 0 0 0 0 1 60: 1 1 2
Each "place" in the number system represents a prime number. Given n, return the vector p.
As shown above, if n = 26, then p = [1 0 0 0 0 1].
The input n is always an integer greater than 1. Suppress any leading zeros. The length of the vector is determined by the largest prime factor.
I think the explanation in the problem statement is a bit sparse. The numbers in the table do not represent prime numbers per se: they represent indices on prime numbers, whose ultimate product yields the value n.

The in-built function factors() was pretty helpful for this problem :)
I do not understand how this code passes the test.
how can i see this solutions？
tabulate code is not working. I got the correct results but I am getting error --"Undefined function 'tabulate' for input arguments of type 'double"
Tabulate could probably be made to work here, but I recall that Cody does not allow toolbox functions, and tabulate lives in the stats toolbox. I'd guess the logic is that not everyone has all toolboxes, so a solution that uses some tool that others cannot use would not be fair to those others.
Definitely used a bit of a work around in this one. Sorry for that!
great problem...
can't believe 'deblank' can be used in this way
