Hi

I want to create a vector that have the value of 1 in specific intervals and 0 everywhere else.

This is the code I have come up with but it doesn't work. flagstart indicates where the intervals with 1s should start and flagstop where they should stop so that there are 5 intervals (11600 to 22620 and so on)

res=zeros(151001,1);
flagstart = [11600 42410 72480 102100 132000];  
flagend = [22620 52410 82550 112900 142200];
res(flagstart,flagend) = 1;
