| The Van Der Pol oscillator is a simple problem with two equations | ||
| and two unknowns: | ||
|
|
||
| ``` julia | ||
| function Vanderpol() | ||
| y = Unknown(1.0, "y") # The 1.0 is the initial value. "y" is for plotting. | ||
| x = Unknown("x") # The initial value is zero if not given. | ||
| @variables x(t) y(t) |

Suggested change
| @variables x(t) y(t) | |
| @variables x(t) y(t) = 1.0 |
can be allowed now that there's the metadata @YingboMa?

Interesting. A knew metadata was coming, but I haven't seen examples. Initial values in variables would be great.

Any hints on how to programatically create a variable that has an initial value? I am currently using Num(Variable{ModelingToolkit.FnType{Tuple{Any},Real}}(gensym("i")))(t), and I also see setmetadata.

We want to allow interpolating into the macros, i.e . x = @variables $y = 1.0
