you're overwriting it with the p(n) as n only goes from 1 to 10 again and again. you'll have to increment p(#) beyond n or multiple of #*(1:10)
collectnum = 0;
while abs(angz) < 360
for n = 1:10
q = a.gyroRead('z') - dc_offsetz;
if abs(q) > threshold
dt = toc(timer);
angz = (angz + (q/32768)*sensitivityz*dt - gyro_driftz);
p(collectnum*10+n) = angz; %so you're increasing the index for every 10 points collected
end %added these end lines to show where you'll need to put the increment of 10 line
end
collectnum=collectnum+1; %need this after the end in your for loop to increment the multiple of 10.
end
