How do I count how many times disp() appears in the command window

Hi,

I am doing parallel computing with Matlab, the question is simple, how to count how many times disp() appears in the command window.

For example:

N=100;
count=0;
parfor i=1:N
    disp(i);
end
%% Here is the problem, when doing parallel computing, I can't count in the loop. So, I want to to count outside the loop
if disp()
   count=count+1;
end

parfor understands how to handle addition in parallel. Hence you can simply increment a variable as follows,

N=100;
count = 0;
parfor i = 1:N
    count=count+1;
end

If this does not work for any reason, you can create a vector of length N, and use it to count whether i-th iteration called disp.

N = 100;
count = zeros([N, 1]);
parfor i = 1:N
    % if disp called
    count(i)=1;
end
