How do I find a pattern in an array

So this is what needs to happen, i've created this rythm in Matlab: 1 0 0 1 0 0 1 0 0
Whenever the pattern 1 0 0 occurs I wanna play sound X, 0 1 0 play sound Y and 0 0 1 I want sound Z to play.
This is my code until now:
ritme = 1 0 0 1 0 0 1 0 0
loop = length(ritme)
l = 1;
sound = mat2str(ritme)
bass = "1 0 0"
hihat = "0 1 0"
snare = "0 0 1"
while l <= loop
for i=1:8
if ritme(i) contains(sound,bass);
soundsc(kick,Fs)
elseif ritme(i) contains(sound,hihat);
soundsc(hat,Fs)
elseif ritme(i) contains(sound,snare);
soundsc(snare, Fs)
end
l = l + 1;
pause(0.3)
end
end

Hey @N/A, I assume that each time you compare 3 concecutive numbers from 'ritme' and based on the pattern it matches play that particular sound you can achieve this by making minor changes in your code as suggested below:
% Iterate over the rhythm pattern
for i = 1:(loop - 2)
% Extract a segment of the rhythm pattern
segment = ritme(i:i+2);
% Check which sound to play based on the pattern
if isequal(segment, bass)
% Play the kick sound
soundsc(kick, Fs);
elseif isequal(segment, hihat)
% Play the hi-hat sound
soundsc(hat, Fs);
elseif isequal(segment, snare)
% Play the snare sound
soundsc(snare, Fs);
end
% Pause for a short duration
pause(0.3);
end
