# MATLAB: Make a vector of 1’s and zeros

vector; sort; find

I could like to make a matrix consisting of 1's and zeros at certain points. I have a vector that is made up of two other vectors; C = [ A A1] and B = sort[C]
I wish to make a vector that is one at the points A and zero at A1. Because these are interspersed I am confused on how to do this. I tried using find but because A has a different length to C I cant use it for this purpose. Any ideas would be great 🙂

• A=[1 2 3 4]B=[2 6 1 5][C,idx]=sort([ A B])C(idx<=numel(A))=1;C(idx>numel(A))=0
