Sorting data by ascending at sampled points, and using 1-D Lookup table to select highest OR lowest value.

In my Simulink model; at every point of triggered sampling, I have 4 voltages which are measured at the same time and must be sorted into ascending order (lowest measured voltage value up to highest measured voltage value). Afterwards I want to select the highest measured value out of the 4, or the lowest measured value out of the 4.
I'm certain it is the 1-D lookup table and sort blocks which are required to be used, but there must be others as well, but I am not sure which ones? What command(s) is required to select the highest or lowest values?
EG:
Measured Values: [ 2 4 3 1]
Then to place into ascending order:
[ 1 2 3 4]
Then a command to select highest or lowest:
highest = 4
lowest = 1
I hope it is clear, it's quite straight forward I presume and I hope, I just haven't got the experience using Simulink, and the documentation doesn't really help.
Many thanks!

OK, I "know nuthink" as per Sgt Schultz specific on Simulink but afaik you can use Matlab functions as blocks. To my surprise I didn't find a SORT block in the online doc's so you could use the Matlab sort() function. It returns the input vector sorted so the given outputs will be in a specific location. If you need the original position(s), it also has a second optional output that is the index vector of locations in the original.
