Unlike in Maniplate where can see one instance at a time displayed, I wish to see separate Boxes at first and then next see combined Plot together by Show.

Hi, I have Mathematica HStudent Edition, version 9.0.1.0 When I open a notebook from a directory, let's say /Users/jl/mnbs/info content/ and work on it, but in the meantime I decide to rename the directory to /Users/jl/mnbs/infocontent/ that is I take out the space between info andhttps://groups.google.com/d/topic/comp.soft-sys.math.mathematica/OeDSgHpVLgM

Am I overlooking commands to produce numerical gradient, Jacobian, and Hessian? The closest I could find was ND (in the NumericalCalculus package), which seems to be only for univariate functions. Thanks, Alan Isaachttps://groups.google.com/d/topic/comp.soft-sys.math.mathematica/K-AJX1pkmRk

Two years ago this answer was given: http://mathematica.stackexchange.com/questions/2821/does-mathematica-have-advanced-indexing Essentially, the answer was that Mathematica did not provide direct support for this feature (unlike say NumPy, R, etc.). Work arounds were suggested. Has thehttps://groups.google.com/d/topic/comp.soft-sys.math.mathematica/-HPLBXehNLw

https://groups.google.com/d/msg/comp.soft-sys.math.mathematica/zkhzqr0l2nQ/1GZh_m9mgP0J
Dear Dave, many thanks again. Now I have the problem to tell Mathematica that same variables are reals and have not to be 'starred' so that (x+Iy+z)* is not x*+Iy*+z* but x-Iy+z* (if x and y are reals and z unknown. Command like Element[x, Reals] does not work. Sincerely yours Robertohttps://groups.google.com/d/topic/comp.soft-sys.math.mathematica/zkhzqr0l2nQ

I have defined the following useful star complex-conjugation (common star exponent notation) f_*:=f/.Complex[u_,v_]->Complex[u,-v] and it works fine. For example BesselJ[2,x+I y]* gives BesselJ[2,x-I y] etc...(x,y defined/undefined). Also it is listable on number lists {1+i2, 5+i6}*https://groups.google.com/d/topic/comp.soft-sys.math.mathematica/EPqUx3GE_ig
