how to formulate logical matrix in a loop?

i am having a matrix and want to separate them in the depending on its value
A=[1,2,3,4,5,6,7,8,9,10]
expected result are
idx1=[1,0,0,0,0,0,0,0,0,0] % for 1
...
idx10=[0,0,0,0,0,0,0,0,0,1] % for 10

A=[1,2,3,4,5,6,7,8,9,10]
RESULT = zeros(1,numel(A));
RESULT1= RESULT;
for i = 1:numel(A)
idx(i)=A(i)==1;
idx1(i)=A(i)==10;
end
RESULT(idx) = A(idx)
RESULT1(idx1) = A(idx1)

No need to use logical indexing , see the above illustration
how can form a loop for this?

See the edited answer ,problem solved!
A=[1,2,3,4,5,6,7,8,9,10]
idy=zeros(1,length(A));
for i=1:1:10
idx22=find(A >=(i) & A<(i+1));
idy(i,idx22)=1;
end

i have created a array
in which at evry row the numbers are indexed in a step of 1
from this array i can use evry row as a vector
and important is that, its done in a loop so i do not have to repeat the operation 100 times
try the updated code to get a clear idea

I know but you don’t have Use a loop
A=[1,2,3,4,5,6,7,8,9,10]
idy=zeros(1,length(A));
for i=1:1:10
idx22=find(A >=(i) & A<(i+1));
idy(i,idx22)=1;
end
