Hello, I have a data of Patents from OECD in delimited text format with IPC code being one column, I want to filter the data by selecting only certain IPC codes in that column. Please, can anybody guide me doing it, also the IPC codes are string variables.

Probably the easiest way is to readtable() and then select only the rows where the desired codes are, probably using ismember
selected_data = TheTable(ismember(TheTable{:,ColumnNumber}, ListOfDesiredCodes))
