How do I repeat elements individually in a row
显示 更早的评论
I have a matrix of several thousand rows each of which is 16 bits representing an integer. In order to simulate 3,1 error correction I have to replicate each bit 3 times. I am currently doing this using for loops, I have read about kron and repmat and they seem that they would be more efficient for this but I can't figure out how to use them properly to do it.
Small example
1111 becomes 111 111 111 111 (without spaces they are there for clarification)
0000 becomes 000 000 000 000
1010 becomes 111 000 111 000
