I need to recombine two vectors which where seperatet by logical indexing:
idx = [1 0 0 1 1 0 0]; % appearance of logical index
a = [2 3 4]; % the values of a have to replace the ones in indx in the same order
b = [9 8 7 7]; % the values of b have to replace the zeros in indx in the same order
The solution should look like this:
c = [2 9 8 3 4 7 7]; % recombined vector

b = [9 8 7 7];
c = [a b];
idx = logical(idx);
c = [c(idx) c(~idx)]

Try this:
idx = [1 0 0 1 1 0 0]; % appearance of logical index
a = [2 3 4]; % the values of a have to replace the ones in indx in the same order
b = [9 8 7 7]; % the values of b have to replace the zeros in indx in the same order
c = [];
aIdx = 1;
bIdx = 1;
for i=1:length(idx)
if idx(i) == 1
c(end+1)=a(aIdx);
aIdx = aIdx + 1;
else
c(end+1) = b(bIdx);
bIdx = bIdx + 1;
end
end
c
