Hi, I need some help shortening this fragment of Julia code
https://gist.github.com/berceanu/e4fdfa6285d30c024a71 The main idea is that *ft* and *ftex* are both tuples containing 4 anonymous functions. The are initialized as the identical function, but then depending on the toggle buttons, can take 2 separate sets of values. The important thing to notice however is that between the 2 *togglebuttons* instances, the anonymous functions (for each branch) are the same except for an overall minus sign. What I would like to do is have a single *togglebuttons* instance, which sets the value of *ft* and then *ftex* should get the same value, but with minus signs in front of al the anonymous functions. How can this be achieved? //A
