I have matrix A which is 1x276 and B which is 1x503305. I want to count how many values from B are greater or equal to each value of A. How would I do this?

Thanks!

arrayfun(@(x)sum(x>=B),A)

or perhaps I am reading it wrong and you need to swap A for B and vice versa

I had to swap A for B, but this is correct! I learned a new function today, thanks!

Happy to help! :)

Arrayfun is basically a nicer way to loop over the elements of an array. Note that it is often slower than looping, so if you have very large data sets you may want to loop instead.
