if x>=3.3
disp('signal recevied soil is dry time to water')
writeDigitalPin(a,'D2',1);pause(0.2);writeDigitalPin(a,'D2',0);
elseif x>=2.9
disp('signal received soil is wet but not wet enough time to water')
writeDigitalPin(a,'D2',1);pause(0.2);writeDigitalPin(a,'D2',0);
else
disp('signal received soil is wet')
end
how do i make a loop that keeps running through this if statement until the value of x is <2.9

Ran in:
for x = 0:0.1:5
if x>=3.3
disp('signal recevied soil is dry time to water')
writeDigitalPin(a,'D2',1);pause(0.2);writeDigitalPin(a,'D2',0);
elseif x>=2.9
disp('signal received soil is wet but not wet enough time to water')
writeDigitalPin(a,'D2',1);pause(0.2);writeDigitalPin(a,'D2',0);
else
disp('signal received soil is wet')
end
end
signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet signal received soil is wet
