Have two thresholds (control limits) - one that defines low bad data, and one that defines high bad data. Then just see if any elements are outside of your range

badDataLocations = data < lowThreshold | data > highThreshold; % Map of bad data locations.  (Use single vertical bar, not double).
hasBadData = any(badDataLocations(:)); % Boolean flag to indicate that you have bad data somewhere.

What do you mean by tolerance? I gave you code to determine which, if any, values in a numerical array were outside of some acceptable range. What more or different operations do you want? Please explain in detail with some actual numbers that are both within tolerance and outside of tolerance. First, read this then give actual input and output values as an example.
