The title basically. A typical example is the co-ordinates of a particle, and I want to introduce time dependence to define it's trajectory. For example, if I have cartco = {x,y,z}, I want to automate the defining of cartcofn[t] = {x[t],y[t],z[t]}. I can use Table command to make a loop over the list as I am doing for the moment, but is there an inbuilt function, like can Thread be somehow used?

    $\begingroup$ Welcome to MMA SE! here's one way: c = {x, y, z}; cf[t_] = (#[t] &) /@ c Does that get you what you're looking for? $\endgroup$

  • $\begingroup$ yeah works. Thank you. Making the name of the name of function the dummy variable to replace, nice trick. $\endgroup$
