MATLAB: Find the max values within a matrix, in the range of the highest value and 10% lower.

Question

Hello,

I have a matrix with a random set of numbers, I can find a list of the highest numbers using the code below. However how do I modify this to return the values within the range of the highest value and 10% below the highest value?

HC = find(zz == max(zz(:)));

Thanks in advance.
