MATLAB: Vertical concatenation of matrices in a loop

vertivally concatenate matrices

I have a set of matrices saved in a data structure. I need to vertically concatenate the matrices. The number of columns is consistent for every matrix. how is it possible to do this in the loop i have written here. thanks
    for fileNr =1:8
     outputFileName = outputFileNames(fileNr);
    outputFileName = outputFileName{1};
    outputFileName = strcat(outputFolder, filesep, outputFileName);
    FileName=(outputFileName);
    FileName
    data1=load(FileName);
    data=data1.dataStruct.data;
    end

Yuvashree, try
 data = [];
 for fileNr = 1:8   
    [...]                  % removed code for better readability
    data1 = load(FileName);
    if (rem(fileNr,8)==0)  % save every 8th matrix
       data = [data; data1.dataStruct.data];
    end
 end
