It works fine. However, I had some other trouble while defining my functions with cabs. For instance, the code simp:false$ define(y(x),log(cabs(1/(1+exp(%i*x)))))$ simp:true$ y(1.0); does not evaluate completely the numerical value. But it works if I use ":=" to define the function. Here the code simp:false$ y(x):=log(cabs(1/(1+exp(%i*x))))$ simp:true$ y(1.0); evaluates perfectly. I actually need to set "simp" to "false" because the expressions I deal with in my real case are quite complicated. I need to prevent a simplification at this stage to avoid MAXIMA to start an endless evaluation while defining my expressions.
