I want both the nodeCrd and edgeList to display, but I'm only able to get the first one listed to display.

function [nodeCrd,edgeList]=ReadInputData()
       filename="inputdataa.txt";
       fileId = fopen(filename,"r");
    if (fileId == -1)
         disp("Could not open the file !")
         return
    end
    % read the first line
    tempLine = fgetl(fileId);
    disp(tempLine)
    
    % read the second line
    tempLine = fgetl(fileId);
    disp(tempLine)
    % there is a pattern here (node's coordinates + IsSupport)
    data = textscan(fileId,"%f %f %f %f %f %d");
    % convert it to array
    nodeCrd = cell2mat(data(1:5));
   
    % pattern is finished at this line 
    % let's read that line
    tempLine = fgetl(fileId);
    disp(tempLine)
    % there is another pattern here (memebrs)
    data = textscan(fileId,"%f %f %f" );
    % convert it to array
    edgeList = cell2mat(data);
end
