Real sym
Specifically, I'm looking at a function that involves the phrase a = !!sym("x") where "x" is a string. I thought sym worked by turning a string into an object, so a = sym("x") would set a equal to the object x. What is the !! there for? I read that it unquotes whatever is after it, but I thought sym itself unquoted strings?
Creating symbolic expressions. First, let's use the @syms macro to create a few symbols. using SymbolicUtils @syms w z α:: Real β:: Real. (w, z, α, β) Type annotations are optional when creating symbols. Here α, β behave like Real numbers. w and z behave like Number, which is the default. You can use the symtype function to find the type ...
