how to remove index exceeds matrix dimensions in matlab?reply me.

num_images = numel(filenames);        %num_images=165
image_dims = [40 40];
images = zeros(prod(image_dims),num_images);
PI = 11;      images per person
P = 15 no. of person
id = zeros(20,PI);
for i = 1:20                        % i is runs time means i run 10 times
    id(i,:) = randperm(PI);
end

save id

run = runs + 1;
for k = 1:run
    disp(k);
    m = id(k,:);
    for i = 1:15   
    for j = 1:11
        ind = (i-1) * 11 + j;
            if (m(1) == j) || (m(2) == j)
            ind1 = [ind1 ind];
         else
            ind2 = [ind2 ind];
            end
    end
end

train = images(:,ind2);
test = images(:,ind1);

In your line

run = runs + 1;

runs is not defined.

You need to post the complete error message, so that we do not need to guess about which line the error is occurring on.
