How to find maximum values in large dataset

hello everyone, I have one large data set as a one column matrix and the size (3386718 x 1) and I need to filter some maximum values inside the data. For example most of the values between 0-1 but the some values about 14 and 15.. so I try to find out max values. However I've got this error message

displace=data

c=max(displace)

Subscript indices must either be real positive integers or logicals.

how can I find the max values and remove them from dataset??

Thanks. Mustafa

First of all, 3 million elements not a large dataset by any modern definition. It's like 1/10th the size of a typical point and shoot camera image. Anyway, you can simply threshold to get a map of where the outlier pixels are:

badElements = displace > 1; % Or whatever value you want.

To remove them from your array, do this:

displace(badElements) = [];
