Command to pad zeros to specific locations in binary numbers?

Question

I need to pad zeros to specific locations in binary numbers. Looping the array form of a binary number such as dec2bin(43) and adding the zeros and adjusting th

Answer 1

You can do it using just indexing. The positions of the zeros to be inserted in the extended vector are insertzeros+(1:length(insertzeros)) (where insertzeros is [1 3 6] in your example):

input = [1 0 1 0 1 1]; %// example data
insertzeros = [1 3 6]; %// example data

output = ones(1,length(input)+length(insertzeros));
output(insertzeros+(1:length(insertzeros))) = 0;
output(output==1) = input;
