Stop for loop if value is bigger than 10

3 views (last 30 days)
Hi,
I want to add a while loop and start the for loop again if a value in dx > 10. So I have to stop the rest of the loop and startover for the next for loop.
Check my script where i want to add the while loop.
for i1 = 1:length(RCA);
fullfilename = fullfile(RCA(i1).folder, RCA(i1).name);
thisData = readmatrix(fullfilename, 'Range', 2, 'Delimiter', ',');
sample_dist = thisData(:,1);
step = (max(sample_dist)-min(sample_dist))/2499;
a = min(sample_dist):step:max(sample_dist);
XYZ = [thisData(:,7),thisData(:,8),thisData(:,9)];
vq = interp1(sample_dist, XYZ, a);
dx = vq(:,1) - vq(1,1);
dy = vq(:,2) - vq(1,2);
dz = vq(:,3) - vq(1,3);
vq(1,1) = 0;
vq(1,2) = 0;
vq(1,3) = 0;
% here i want to check if any value in dx is bigger than 10. if yes
% start the for loop again for the next set. If no continue this loop
plot3(dx,dy,dz)
legend(strcat(i1))
hold on
afstand=[1:2500, i1];
lengte = size(dx);
lengte = round(lengte);
row = 0;
for i2 = 1:1:lengte-1
row = row+1;
P1 = [dx(i2), dy(i2), dz(i2)];
P2 = [dx(i2+1), dy(i2+1), dz(i2+1)];
P(i2,1:3) = [dx(i2), dy(i2), dz(i2)];
angleradian2(i2) = acos((P2(2)-P1(2)) / norm(P2-P1));
distance(i2) = norm(P1 - P2);
end
avgrad = mean(angleradian2,'all','omitnan')
for i2 = 1:250:lengte-250
row = row+1;
P1 = [dx(i2), dy(i2), dz(i2)];
P2 = [dx(i2+250), dy(i2+250), dz(i2+250)];
P(i2,1:3) = [dx(i2), dy(i2), dz(i2)];
% angleradian2(i2) = acos((P2(2)-P1(2)) / norm(P2-P1));
angleradian3(row,i1) = acos((P2(2)-P1(2)) / norm(P2-P1));
distance(i2) = norm(P1 - P2);
end
angleradian2 = angleradian2(:,1);
afstand = afstand(:,1:2500);
end

I think what you need is the 'continue' command, try
...
% here i want to check if any value in dx is bigger than 10. if yes
% start the for loop again for the next set. If no continue this loop
if dx > 10
continue
end
plot3(dx,dy,dz)
...
or you can check https://www.mathworks.com/help/matlab/ref/continue.html for more information

dx is not a value, its a list. So I have to check if any value in dx is > 10. How can i see that?

Then just fix it as follows
...
% here i want to check if any value in dx is bigger than 10. if yes
% start the for loop again for the next set. If no continue this loop
if any(dx > 10)
continue
end
plot3(dx,dy,dz)
...
