I want to check that the Value of one array exist in another array, using function ?
显示 更早的评论
RemainingSensor=[1 2 4];
Cover=[1 3];
[m,n]=size(RemainingSensor);
for i=1:m
for j=1:n
r=RemainingSensor(i,j);
a=funcCover(r);
display(a);
end
end
function c= funcCover(v)
[s,t]=size(Cover);
for i1=1:s
for j1=1:t
k=Cover(i1,j1);
if k==v
c=k;
end
end
end
end
first array is "RemainingSensor" and wants to check that the of this sensor existe in other array that is "Cover", how it is possible?

It is possible using the function ismember
RemainingSensor=[1 2 4];
Cover=[1 3];
validsensors = ismember(RemainingSensor,Cover);

Then I'd just use funcCover as a function calling ismember.
Regardless of what you do you'll have to have two inputs to your function, as your variable 'Cover' is never sent to your function funcCover as long as it only have one input.
RemainingSensor=[1 2 4];
Cover=[1 3];
[m,n]=size(RemainingSensor);
for i=1:m
for j=1:n
r=RemainingSensor(i,j);
a=funcCover(r,Cover);
display(a);
end
end
function c= funcCover(v,W)
if ismember(v,W)
c = v;
else
c = 0;
end
end
