Hi all,
I have a shape file (shp) that is read as a structure within MATLAB. It is a 2540x1 struc in the worksapce. One of its columns is character type. chr. I want to find a few names in it like 'Malta', keep the entire row that includes the Malta and then remove all other rows. Could you please teach me how to do that?

Please post a short example of how your data look like. I do not understand "One of its columns is character type. chr." Structs do not have "columns".

placenames = {YourStruct.PlaceNameField};
wanted_mask = ismember(placenames, {'Malta', 'Paraguey', 'Lake Wawa'});
selected_members = YourStruct(wanted_mask);
