stats = graycoprops(Imggray)

Hi ,I am using this built-in function which gives me four values in structure format. Now i want to run this code in loop and store these 4 values for each data set in a CSV or txt file. The values are not getting appended rather gets overwrite.

You can use dlmwrite with the “append” property.

Here’s a rough sketch of the code for your reference

for = 
    ...
    stats = graycoprops(Imggray)
    if(~isfile('test.csv'))
        dlmwrite('test.csv', struct2array(stats), 'delimiter', ',');
    else
        dlmwrite('test.csv', struct2array(stats), 'delimiter', ',', '-append');
    end
    ...
end
