Hello,

I would like to make "if" loop by using strings. So if the string is: 'Cor' or 'Sag', do main_LA, else if the string is:'Tra' do main_SA;

if DI.Orientation == strcomp('Cor'|| 'Sag')
    main_LA;
else DI.Orientation == 'Tra'
    main_SA;
end

Is that the right way of doing it? Thanks, I

Ivan - your use of strcmp is not quite correct. To compare whether the orientation is either Cor or Sag, you would need to do the following

 if strcmp(DI.Orientation,'Cor') || strcmp(DI.Orientation,'Sag')
     main_LA;
 elseif strcmp(DI.Orientation,'Tra')
     main_SA;
 end

The above assumes that orientation is one of the above three strings. If you wish to ignore case (upper or lower), the use strcmpi.
