Hi, I was trying to follow the instruction on "fitting with an ordinary differential equation". But I always encounter the compiling error of "Variable "struct user { double a; }" not declared" .
Did you follow this tutorial? I tried it on my machine and everything works as expected. Did you include these lines before you define the static function?
struct user // parameter in the ODE { double a; };
Also, you can double-click the red error message to go to the line that error exists.
Compile error: variables not declared
