curve fitting tools such in scipy tend assume parameters of model functions real-valued. when fitting model depends on complex-valued parameters complex-valued data set, 1 therefore first has create version of model, in each complex parameter replaced 2 real ones. first, simple example: # original function, representing model a,b may complex-valued def f(x, a, b): return a+b*x # modified function, complex parameters have been replaced 2 real ones def f_r(x, a_r, a_i, b_r, b_i): return f(x, a_r + 1j*a_i, b_r+1j*b_i) print( f(1,2+3j,4+5j) == f_r(1,2,3,4,5) ) note: output of model still complex-valued, can taken care of appropriately defining residual function. now, instead of having write new code every function f , have "function factory" pass function object f list of booleans is_complex specifying arguments of f assumed complex-valued (and therefore need replaced 2 real-valued arguments). list of booleans e.g. inferred initial values provided f . ...

i tried implement nested recursive function in python giving error "runtimeerror: maximum recursion depth exceeded" can see function in following code. regarding question appreciated. n=10 def test(n): if n<=0: return 1 else: return test(test(n-1)+1) print test(n) one important part of recursion every recursive call have closer anchor case, in case is: if n<=0: return 1 however, code not getting close case. problem line: return test(test(n-1)+1) since test returns 1 when reaches end case , add 1 result, let's see happens when call test(2) : the anchor case isn't executed , go straight else . return test(test(1)+1) since 2-1=1 . inner test call going go else case , call: test(test(0)+1) here inner test call returns 1 (it has reached end case) means in line calling test(2) //test(1+1) again. here can see recursion never ending, hence maximum recursion depth exceeded error . just clarify how ma...

i'm using mix of .ready() , .load() execute desired function. jquery(document).ready(function($) { $("img").load(function() { // function goes here }); }); as can see, waits dom ready, on each <img> load, executes code. if had 1 image load simple. but problem -- if have 10 images loaded? function called 10 times due each image loading 1 one, , that's not efficient way go achieve want. so here's question -- there more efficient way wait images load, execute function once ? you avoid having function run multiple times. jquery(document).ready(function($) { var nrofimages = $("img").length; $("img").load(function() { if(--nrofimages == 0) { // function goes here } }); });
