Finding 3 largest values in a matrix

Consider I have a large matrix (say 24*30), is there a way to find the three largest values?

I know that we can find the biggest value using this command:

max(A, [], 'all')

But is there another way around this?

If you have R2017b or later, the maxk function will likely be useful.

I tried it, but it is giving me the biggest element in each column. So giving me 30 values if i set k to 1

maxk(A(:),3)
