content of text file exploring, how?

FileName='Q4.txt';
fileID=fopen(FileName);
CellOutput=[]
Delimiter=','
while feof(fileID)~=1;
    a=fgetl(fileID);
    a=strsplit(a,Delimiter);
    for count=1:1:length(a);
        Temp=str2num(a{count});
        if ~isempty(Temp);
            a{count}=Temp;
        end
    end
    CellOutput=[CellOutput;a]
end
fclose(fileID);
TextOrNum=[]; %This line can be deleted after you are done coding this function.
%%Start your code for this function after this line:
TextToCheck = importdata('Q4.txt')
Numeric= TextToCheck.data
TextToCheck.textdata(2:end,3:end)=num2cell(Numeric)
TextOrNum= TextToCheck.textdata
for i= 1:length(TextOrNum)-1
    Fmax{i}=max(Numeric(i,:))
end
Material= TextOrNum(2:end,2)
MaterialxFmax=[Material,Fmax']
SaF=[]
for j=1:length(Properties)
    same=ismember(MaterialxFmax(:,1),Properties(j,1));
    if same==1;
        SaF=(MaterialxFmax(j,2)/Properties(j,2))
    end
end

why is this code not running?

Attach your data.

It may not be running becuase, the text file is not in the prest working directory. Check the value of fileID.

If not, is it throwing any error? You have to specify the error.
