Stopping a MATLAB loop after certain condition

above is my plot of my ship heading(blue) and rudder angle(red), i'd like to stop my loop after the red line data have 4 value of 0 (or aprox. 0).

red line data is 2 row vector of array with double precision (in case you wonder).

i know it's a simple condition but i just don't know how to make the script.

could anyone tell or show me how to do it? i appreciate it.

Rudder = repmat([rand(1,5), 0, rand(1,5), 0, rand(1,5), 0, rand(1,5), 0],2,1)

Rudder = 2×24

0.9995 0.4196 0.6164 0.8721 0.6362 0 0.8652 0.3240 0.3273 0.1284 0.3913 0 0.2856 0.4808 0.7988 0.0282 0.3477 0 0.0671 0.2529 0.0200 0.2973 0.0620 0 0.9995 0.4196 0.6164 0.8721 0.6362 0 0.8652 0.3240 0.3273 0.1284 0.3913 0 0.2856 0.4808 0.7988 0.0282 0.3477 0 0.0671 0.2529 0.0200 0.2973 0.0620 0

count = 0;
for x = 1:size(Rudder,1)
    for k = 1 : length(Rudder)    
        if Rudder(x,k) == 0
            count = count + 1; 
        end
        if count >= 4 
            break;         
        end 
    end 
end 
count

count = 4

compare the values in the Rudder array as above

yup! i works with some modification

thanks mate!!
