How can I get "least frequent" number from a vector?

I know that "mode" is used to get the most frequent number in a vector. Is there any function that returns the "least frequent" number?
For example, a vector: 1 1 2 2 3 3 4 5 5 5 returns 4 since this number only appears once and all others appear more than once.
I guess I can solve this problem use "unique" and "hist", but I am just wondering if there is any better solution than that.
Thank you very much.

Option 1: You can copy the code from mode.m and replace the function max by the function min on line 130 (in R2014a). Edit the help text accordingly, and save.
Option 2.
V = [2 2 1 1 4 5 5 5]
uv = unique(V)
n = histc(V,uv)
[m,i] = min(n)
minmode = uv(i)

In Option 1, in Matlab 2018b, you need to replace the max with a min in line 163, but also replace the "zeros" with "inf" in line 161.
