I have a matrix "A" that is a 350×1 matrix that is populated with numbers from 0-10, but these numbers are not all intigers. For example there are 6.7, 9.1 along with the intigers in the data. I have caluculted the 25th percentile to be 8.4. I want to remove every number above 8.4 from the matrix as I am no longer interested in those numbers. How would I do that?
