I've just discovered the new command DSolveValue in Mathematica 10. Is this new command now the preferred instead of DSolve? Is it the better command to teach to students? Same question for NDSolveValue, ParametricNDSolveValue?

    $\begingroup$ This seems to be primarily opinion-based. Each has their uses, depending on the ways in which you wish to use their output. WRI added them because users wanted all the various ways of getting the output prepackaged, or so they said at WTC this year. FWIW, for my uses, I prefer DSolve, NDSolve, and ParametricNDSolveValue. $\endgroup$ – Michael E2 Dec 28 '14 at 21:15
  • $\begingroup$ At first I thought about ParametricNDSolveValue: "this is the most absurd function; why would anyone bother to implement this trivial wrapper around ParametricNDSolve?". But then I used it, and it seemed at least somewhat worthwhile. So, they definitely have their uses, although I wouldn't say they're in any sense "preferred"--they're just wrappers, provided for your convenience. The preference is up to you. $\endgroup$ – Oleksandr R. Dec 29 '14 at 0:09
