I am trying to define a piece-wise function over several different intervals. However, the indicator function won't let the function evaluate for a specified input value. It keeps telling me that input argument a is undefined. I can't seem to figure out what I am doing wrong though. Here is what I have:
v = @(t,a,b) (t>=a) & (t<b);
f=@(t) 0.*v(t<0) + 2*t.*v(0<=t & t<0.5) + 0.*v(t==0.5) + ...
(2*t-2).*v(t,0.5,1) + 0.*v(t>=1)
t=[0:0.01:1];
The program won't let me evaluate f(t). Also, am I allowed to set the intervals as logicals or do I have to have values? This is not covered in my book or in my lecture notes. Thanks for the help.
