COMSOL expression evaluation

In COMSOL I am using two expressions to calculate a certain parameter, and the objective is to pick the one that under given conditions gives a result, which is a real number and 0<=x<=1). I can easily plug a MATLAB routine to do the assesment and pick the value calculated from either of the two expressions, but I always consider the use of MATLAB from COMSOL as last resort, so maybe there is a way to do it with some smart formula in COMSOL?
Any help will be very much appreciated,
Mike

you could try to use boolean expressions, like
x*(x>=0 & x<=1) This would result in the value of x between 0 and 1 and 0 elsewhere.

Is it x*(x>=0 & x<=1) OR x*(x>=0 && x<=1) ?

have you read te help on "Special Operators" and "Unary and Binary Operators"
seem to go more towards && and || in COMSOL;)
