 | Hey everyone,
I've got a model that I'm trying to debug and I've realized that I get
into trouble when I use the expression block. Specifically I've got one
expression block with two inputs (x2 and x8) and inside the block the
expression:
.1*(x8/(0.1+x8))-x2
I think the problem is with the way I'm using parentheses because I've
reimplemented the above expression using two expression blocks:
Expression2: 0.1*x8-0.01*x2-0.1*x2*x8
Expression3: .1+x8
and then dividing Expression2 by Expression3 using a MultiplyDivide
block. Using the second method I get much better results.
Anyone know what's going on here?
Thanks,
Andrew
