Task View on Numerical Analysis and Differential Equations

Hans,

thanks for the suggestion and sorry for coming so late to the thread. I 
have only a little to add to Ravi's comments.
I like the idea overall.  Nothing prevents you from doing this, but you 
should be committed to getting it up and running and then keeping it 
updated.
Yes completely d'accord with all comments.

If you want to put together a .ctv, please have a look at

vignette("ctv-howto", package = "ctv")

and send me the resulting .ctv.
In addition to concurring with Berend's comments, I also would like to 
mention that numerical analysis (NA) is an extremely broad category.  I 
am not sure how to restrict that in order to make the taskview 
manageable.
I also completely agree with this. I'm not sure what the best way to focus 
the task view is. Maybe differential equations should be in a separate 
(relatively small) view? The experience is that very large task views 
become harder to maintain in the future because the number of packages 
will grow over time.

In any case, I look forward to seeing a new task view.
Thanks & best regards,
Z
How about including (i) convergence acceleration of sequences, (ii) 
fourier transforms/wavelets, (iii) function approximation and special 
functions of mathematical physics?

Best regards,
Ravi

P.S. I have a package called "eiginv" for solving certain types of inverse eigenvalue problems (e.g., generating a matrix of a specific structure with a given set of eigenvalues)

I am wondering if it would be time to have a new Task View, this time
for the subject of "Numerical Analysis and Differential Equations".
The list of packages possibly appearing in such a task view is already
quite long and could, for example, include:

Numerical Analysis and Linear Algebra

Simulation and Differential Equations

bvpSolve	  Solvers for boundary value problems of ODEs
ddesolve      Solver for Delay Differential Equations
deSolve       General solvers for initial value problems of ordinary
             differential equations (ODE), partial differential equations
             (PDE), differential algebraic equations (DAE), and delay
             differential equations (DDE)

PBSddesolve	  Solver for Delay Differential Equations

sde           Simulation and Inference for Stochastic Differential Equations
Sim.DiffProc  Simulation of diffusion processes
simecol       Simulation of ecological and other dynamic systems

and probably many more in the end. I left out the optimization
packages deliberately, but of course there would be a strong hint to
that task view.

If you put pracma in "Numerical Analysis and Linear Algebra", then I feel you should also include  BB and nleqslv under that heading. Both of these do things that can be classified as Numerical Analysis. And both can of course also be used for simulation.

BB  solve  (sparse) systems of non linear equations using spectral gradient methods nleqslv solve systems of nonlinear equations combining global strategies with a Broyden or Newron method.
