Hello
This might seem a really easy question for some of you but I can't fix it.
I need to create a function M-file for the function
f(x) = 1-x if 0<=x<=1 [1] andf(x) = -1-x if -1<=x<0 [2]
I've tried to do this with
if (x >= 0) & (x <= 1) % x is [1]
y = +1 -x; else y = -1 -x; % x is [2] or outside of the domain (y doesn't matter so it can be -1-x
end
However when I try to plot this function it remains just one straight line y=-1-x It is probably something really obvious that I'm missing here but I'm not really experienced with matlab.
