I am reading some MatLab code, but cannot figure out something of things after googling. Here are my questions:

1. What is the result of meshgrid(1:N)?
2. What is the result of cumsum([x, y, z])
3. What is the result of 3*(1:N)

      - m code can run on Octave? and Octave can generate cpp code? - Questioner (20 bytes) 2010-02-14, 15:58:00 (414315)
        
        这样折腾花的功夫更多，还不如自己读明白再重写。 - Amsel (50 bytes) 2010-02-14, 19:10:41 (414329)
