10:22 <SerajewelKS> i'm having trouble defining a function.  i want the function to evaluate the derivative of another function and store that.
10:22 <SerajewelKS> e.g. foo(f) := block(fp(x) := ''(diff(f, x)));
10:22 <SerajewelKS> problem is, '' causes diff to be evaluated at the time i define foo -- i want it to be evaluated at the time i run it
10:24 <SerajewelKS> the syntax seems to be ambiguous enough to make this impossible
10:28 <SerajewelKS> either that or i'm approaching this incorrectly
10:43 <SerajewelKS> this is ridiculous
11:09 <SerajewelKS> i give up
11:14 <lindi-> SerajewelKS: what is fp?
11:16 <lindi-> hmm, i'm not sure if functions can be passed as arguments

11:32 <SerajewelKS> i think i figured it out
11:33 <SerajewelKS> is there an incantation of something like save that will output pre-compiled code?
11:33 <SerajewelKS> so i can edit the file instead of messing around with lisp?
11:34 <SerajewelKS> ah, strinout
11:34 <SerajewelKS> stringout too
11:38 <SerajewelKS> ok, load is not working-- "Load failed for test -- an error."
11:38 <SerajewelKS> god i love messages like this.  it makes me want to play with hand grenades.
12:09 <lindi-> :)

20:24 <SerajewelKS> it seems that maxima has only one mechanism for evaluating things during function evaluation, am i wrong?
20:24 <SerajewelKS> block(fp:diff(f,x)) -- this will basically substitute "diff(f,x)" where fp is used
20:25 <SerajewelKS> block([fp:diff(f,x)], ...) -- this will evaluate the derivative and make fp equal to the result
20:25 <SerajewelKS> so if i want to evaluate several functions at different points, do i have to keep opening new block()s?
