finding the percentage of concordance

• Hello, I want to calculate the percentage of image not presented to image is presented *

function ham_dis = rec_test(train,impostures)

    ham_dis = [];

    for g=1:5

        for   j=1:339

            ham_dis(j,:)= sum(sum(abs(impostures(g,:)-train(j,:))));

            if (ham_dis(j,:) < 7374)
                disp('image is present');

            else
                disp('image not present');

            end

        end

    end

    end

thanks

I have no idea what "the percentage of image not presented to image is presented" means.

Is there a problem with your code? Can't you just count the number?

Before the loop

numberPresent = 0;

In the loop:

if (ham_dis(j,:) < 7374)
    disp('image is present');
    numberPresent = numberPresent + 1;
else
    disp('image not present');

end

After the loop:

percentage = 100 * numberPresent / (5*339);

Hello, thanks for your quick response

my code work perfectly, its an image recognition code to calculate the recognition rate %

bottom line is i want to count all the images with (ham_dis < 7374) and the images with (ham_dis > 7374)

lets say x= (ham_dis < 7374) >> all the images which has less value than 7374 y= (ham_dis > 7374) >> all the images which has bigger value than 7374

percentage between x & y = ??

My code computes that percentage. The percentage more than 7374 is just (100-percentage).
