How do I use randn vs randi vs rand? - MATLAB Answers

WebbWe will be using randi () command for generating random numbers in range. The syntax is randi ( [start,end]). For example, I want to generate a random number between -10 and 10. So I type randi ( [-10,10]) on the Octave command line I get a random number between -10 and 10 as an output, In this case it was -4. http://www.ece.northwestern.edu/local-apps/matlabhelp/techdoc/ref/rand.html cvs.com otchs myorder storelocator
