Hello everyone!

Out of a Struct I want to get a certain value based on the maximum of the maximum of another value. I know it is possible with the max() function which gives me the index of the maximum value. But I can't really combine the information with the other value.

For example I want to get the maximum of "vfzg_w" and the connected value of "tmot" - and all that integrated in an Interval and for loop.

Below is an extract of my code so far. The idea is to just append it with the same structure to the Struct "Statistik", but I don't know if that is possible.

Maybe someone has an idea :)

for new_idx_loopi = 1 : length (MasterStruct.MDF_FileList_fil)
    
    index_10ms =strfind({MasterStruct.Struct_RAW_Rasters.RasterName},{'10ms'});
    
    Index_100_Hertz_Raster=find(not(cellfun('isempty',index_10ms)));
    
    Struct_Import_temp = mdf_import(MasterStruct.MDF_FileList_fil{new_idx_loopi},{MasterStruct.Struct_RAW(new_idx_loopi).Channels(MasterStruct.IDX_CHANNEL).UniqueName}, 'raster', MasterStruct.Struct_RAW_Rasters(Index_100_Hertz_Raster).RasterName);
    
    Struct_Import(new_idx_loopi).Channels =Struct_Import_temp.Channels;
    Struct_Import(new_idx_loopi).Rasters =Struct_Import_temp.Rasters;
    Struct_Import(new_idx_loopi).Meta = MasterStruct.MDF_FileList_fil(new_idx_loopi);
    
    CHANNEL = Struct_Import(new_idx_loopi).Channels;
    sortiert_idx = sort(lower({CHANNEL.DisplayName}'));
    [NuVar sortiert_idx]=sort(lower({CHANNEL.DisplayName}'));
    sortiert_C = CHANNEL(sortiert_idx);
    
    Geschwindigkeit_Struct = sortiert_C(11);
    Temperatur_Struct = sortiert_C(9);

    switch MasterStruct.B_IntervallTyp
        case 'Zeitintervall'
            
            Time_Axis=Struct_Import(new_idx_loopi).Rasters(1).Data;
            
            Interval_Startzeit=Time_Axis(1);
            idxStart=1;

                Aktuelle_Differenz_Time=Time_Axis(time_run)-Interval_Startzeit;
                
                if Aktuelle_Differenz_Time >= MasterStruct.INTERVAL_VALUE_TIME
                    Interval_Startzeit=Time_Axis(time_run);
                    
                    idx_mean = find(strcmp({MasterStruct.Channel_Liste{:,2}} , 'x'));
                    idx_max = find(strcmp({MasterStruct.Channel_Liste{:,3}} , 'x'));
                    idx_min = find(strcmp({MasterStruct.Channel_Liste{:,4}}, 'x'));
                    idx_crit =find(strcmp({MasterStruct.Channel_Liste{:,1}}, 'tmot'));
