Hi guys,
I need to find the 5th high number of a matrix. Using the max() function I can only have the 1st one.
Thanks for helping!

As Iain suggested, sort is a great way to go, but as you mention that you have a matrix, you might want to sort every element of the matrix:
sorted = sort(values(:));
sorted(end-4)

If you want to take care of repeated values:
vals = randi(200,10);
uVals = sort( unique(vals(:)) );
result = uVals(end-4);
