A list of functions in Mathematica?

  1. Jul 9, 2008 #1
    I would like to define and plot a list of functions in Mathematica without
    typing all them, but I can't find the solution.

    Let's say that we want to plot x, x^2, ..., x^10 on interval [0,1].

    This is what I tried:


    This does not work: n appears in the list as a variable. How can I tell the program that
    the current numerical value of n should be used for the power?

    what the hell is #

    funclist = Table[x^k, {k, 1, 10}]

    works exactly how you want it to

    Characters # and & are used to define a function of any argument without naming the argument (it is called a "pure function").

    Actually my first try was the same as your, but it does not work. funclist is assigned the right powers, but Plot reports "funclist is not a machine sized real number at..."

    Funny, if I copy the output of the funclist assignment sentence into the Plot function, then it works. I don't understand why, since the list intended to be plotted should be the same in both cases.

    Hi Lojzek,

    For the specific example you mention, I would do this:

    Code (Text):


    or another example:

    Code (Text):

    funclist=Table[Sin[n x],{n,1,5}]
