How to randomly generate all numbers in the [m, n] limit in matlab?
How to generate all numbers randomly in limit [m,n]
. To generate all numbers from 6 to 12
.. i.e. the sequence should be like [7 12 11 9 8 10 6]
.
r = randi([6 12],1,7);
But this gives the result:
[12 11 12 7 9 10 12]
Here the numbers are repeated and the sequence does not contain all numbers from 6 to 12
.
You can use randperm
to make a list of random numbers between 1 and n
(where n
is the length of your vector) and use that to permute the vector.
v=6:12; n=length(v); I=randperm(n); v(I)
Assuming you are sampling using a uniform distribution.
r = datasample(6:12,7,'Replace',false)
In a nutshell, this is a random sample with no replacement, so you get all the values from your original population in no particular order.
