Answered: the cyclist on 3 Sep 2015

From a set of data, I want to get 5% or 10% highest figures; and I want to do it based on histogram. The other word, when I plot a histogram of a set of data, I want to get only 5% or 10% of the data in the most right side.

I dont know how I can extract those kind of data.

Define "get". Do you want a gray level image where all but the 5% brightest pixels are masked to black? Do you want a count of the histogram bins past the 95% point? Exactly what does "get" mean to you?

When you say "based on the histogram", that is a bit odd to me. A histogram is a visualization of data. Do you really need that?

If you have the Statistics and Machine Learning Toolbox, you could use the prctile command to find the cutoff, and take elements that are bigger than those.
