i'm trying solve differential equations using fipy in python , newbie, still have problems. following: define cell variable, solve equation variable , update it. want store values after each time iteration. here example: a = cellvariable(mesh,name='a', value=0., hasold=true) # eq equation involving 'a' # define array store values of 'a' after solving 'eq' a_tt = [] t in range(10): eq.sweep(dt=0.01) a.updateold() a_tt.append(a) i realize mistake - values in 'a_tt' updated every time update 'a', have @ end array same elements. shoud alternatively avoid this? i think a_tt.append(a.copy()) might work. otherwise, method used in sweeps part of http://www.ctcms.nist.gov/fipy/examples/diffusion/generated/examples.diffusion.mesh1d.html should work. like: a_tt.append(cellvariable(mesh=m, value=a.value))

i knew basic building blocks of multithreading in wpf, have question quite confusing me. wpf applications start 2 threads: one handling rendering , managing ui. this sounds good,but ui thread bothering me, ui thread nothing application thread the thread creates wpf ui element owns elements , other threads can not interact ui elements directly,this known thread affinity. say,i have 2 text box , 1 button in myapplication , each text box have own dispatcherobject ,on button click i'll update textbox values,hope this'll done ui thread . 1.now,my question ui thread application thread, button have own dispatcherobject , two text boxes have own dispatcherobject , how ui thread has own dispatcherobject , different these ui controls dispatcherobject can update textboxes? my question is, if create new textbox in background thread can update text box ui thread? please correct understanding,i couldn't proceed further. each dispatcherobjec...

one cannot directly use std::get run-time arguments: template<typename tuple> void get(size_t i, tuple const& t) { using std::get; std::cout<<get<i>(t)<<std::endl; //error: 'i' not constant expression } int main() { std::tuple<int,double> t; get(1,t); } however, 1 can manually map run-time compile-time information: template<typename tuple> void get_impl(size_t i, tuple const& t, typename std::tuple_size<tuple>::type) {} template<size_t n, typename tuple, typename = std::enable_if_t<std::tuple_size<tuple>::value != n> > void get_impl(size_t i, tuple const& t, std::integral_constant<size_t, n>) { if(i==n) { std::cout<<std::get<n>(t)<<std::endl; } else { get_impl(i, t, std::integral_constant<size_t, n+1>()); } } template<typename tuple> void get(size_t i, tuple const& t) { get_impl(i, t, st...

my attempts understand generators , sequences lead me idea implement fibonacci sequence. works perfect: struct fibonaccigenerator : generatortype { typealias element = int var current = 0, nextvalue = 1 mutating func next() -> int? { let ret = current current = nextvalue nextvalue = nextvalue + ret return ret } } struct fibonaccisequence : sequencetype { typealias generator = fibonaccigenerator func generate() -> generator { return fibonaccigenerator() } } then decide use sequenceof , generatorof same, stuck on generatorof gives me error "cannot find initializer type 'generatorof' accepts argument list of type '(() -> _)'" next code. var current = 0 var nextvalue = 1 var fgof = generatorof{ let ret = current current = nextvalue nextvalue = nextvalue + ret return ret } but if wrap function works fine: func getfibonaccigenera...

please have following scenario: the app uses password access remote webservice on https; to so, app asks user password, not store on device (and use in safe manner access webservice). my concern following: it's theroetically possible access memory read data contains , retrieve password. please how prevent happening? thanks please how prevent happening? i wear tin-foil hats on professional basis (besides, think spiffy...), , beyond worry about. i'd worry making https code won't victim of martian-in-the-middle (mitm) attack, that's lot easier attacker execute. that being said, samgak alludes in comment, string immutable. once password in string , @ risk attack describe. if use edittext collect password, not call gettext().tostring() user typed in. gettext() return editable , allows @ characters, not string . then, if http client api allows fill in password using char[] , once http request done, can clear out contents of char[] , clear(...

i have correlation matrix named corrdata calculated using numpy.corrcoef . extract 1 or few rows of matrix, , want plot them instead of whole matrix. because matrix no longer square, not possible plot data using pcolor , imshow , or likes. so want ask best alternative way plot these extracted correlation coefficients , same appearance correlation matrix in terms of coloured squares representing value of correlation coefficient, showing few rows of full matrix. you can insert singleton dimension in order turn (n,) 1d vector (1, n) 2d array, use pcolor , imshow etc. normal: import numpy np matplotlib import pyplot plt # dummy correlation coefficients coeffs = np.random.randn(10, 10) row = coeffs[0] # indexing none (or equivalently, np.newaxis) inserts singleton # dimension plt.imshow(row[none, :], cmap=plt.cm.jet, interpolation='nearest') see here more ways convert 1d vector 2d array.
