If statement multiple condition overposing

Does anybody know why this is not working?

It gives me the events that are < and = to zero for the left leg but for the right leg only gives me the events that are > than 0

NoncomplianceIndex = 0;

for i = 1:length(time)

if LeftFrontLegX(i) <= 0 && RightFrontLegX(i) >= 0,NoncomplianceIndex = NoncomplianceIndex + 1; end;

end;

How do the conditions work in matlab? they cannot overlap? if one is <=0 the other one cannot be >=0

Thank you so much

Does anybody know why this is not working?

NoncomplianceIndex=??? % Define may be as zero
for i=1:length(time)
    if LeftFrontLegX(i)<=0 && RightFrontLegX(i)>=0
       NoncomplianceIndex=NoncomplianceIndex + 1;  
    end
end

Same can be done without loop

Sorry I din't show the whole code in order to simplify

No need for a loop.

Noncompliance=sum(LeftFrontLegX<=0 & RightFrontLegX>=0);
