Hello, I would like to delete a row from a 3D matrix. In the 2 column there is a 4 that I don't want thus I need to delete the entire row. I tried using code from the coyote website https://www.idlcoyote.com/idl_way/remove_rows.php but I think my IDL is too old ( I have version 6.7) as it wont allow me to use /NULL with the WHERE function. Any suggestions?
