In a matrix column/array, how can I turn all numbers higher than a certain value into nans?

I have a 1 D array (column) of measured data (that I ultimately append to a matrix). I want to plot the data.

There are numbers higher than "1.0" in the array and they mean that there was a problem with a measurement. I need to turn any numbers higher than 1.0 into nans. Does anyone know how to do this? Thank you for any advice.

The best way is to use logical indexing.

X(X>1) = NaN;

Read this page, especially Indexing with Logical Values:

Thank you very much! Really appreciate the link to the documentation page. I had no idea what terms to search.
