simulazione_1.mat

Hello everyone! I would like to compare each element of the "distance" matrix with each element of the "pos_R2" vector. If the compared values are equal I want to keep the value of the instant i in the vector check_point. Instead, if f is greater than one I want to calculate the average value between f and f-1.

%load variables
load simulazioe_1.m
for i=1:7200
    for j=1:4
if distanza(i,j)==pos_R2(:,1)
            check_point(1,1)=1;
            if f>1
                veloc_ML(m,j)=mean(veloc(check_point(f-1,j):check_point(f,j),j));
                pers_ML(m,j)=mean(num_persone(check_point(f-1,j):check_point(f,j),j));
            end
            f=f+1;
end
    end
end

However this code does not work. How could I do? thank you

Hi. Can you please elaborate on what is m?

m is the time interval between f and f+1

在 MATLAB Online 中打开

load simulazione_1.mat
for i=1:7200
    for j=1:4
if any(pos_R2(:,1 == distanza(i,j))) %Adding any() would do your job 
            check_point(i,j)=1; % Changed from (1,1) to (i,j) but it may depend on your requirement
            if f>1
                veloc_ML(m,j)=mean(veloc(check_point(f-1,j):check_point(f,j),j));
                pers_ML(m,j)=mean(num_persone(check_point(f-1,j):check_point(f,j),j));
            end
            f=f+1;
end
    end
end

You have not stated what is m exactly but i belive it is the index where distance matrix matches with pos_R2 vector. Please specify m and additional query if still you are facing problem.
