I have 3 row vectors, which is defined as y1, y2 and y3. Their dimension is 1*166500. For y1, I want the first value to be zero, for y2, I want first 500 numbers to be zero and for y3, I want first 501 values to be zero, how do I do this? Thanks you!

I mean the index of y2 whose elements I want to set to 0, like for first 500 number within y, I want it to be zero. Thanks you!

I'm such an idiot, I figured it out, it's y2(1, 1:500) = 0 , thanks you!
