Hi,
I'm looking for the right way to set a conditional statement in Simulink. That's the pseudo-code I wish to have:
if x < 6
y = 0
elseif x > 20
y = 2
else
y = 1
The block if is not really what I'm looking for, I just want a small controller with one input (x) and one output (y).
thx

There's at least two ways that I can think of:
  1. Use a 1-D Lookup Table with [0 1 1 2] as the table data and [6-eps 6 20 20+eps] as the breakpoints
  2. Use a combination of Logic and Bit Operations (Compare to Constant and AND blocks).
