i'm computing spectrogram matplotlib. specify nfft=512 resulting image has height of 257. tried stft (short time fourier transform) gives me 512 dimensional vectors (as expected). if plot result of stft can see half of 512 values mirrored 257 values (like matplotlib). can explain me why case? thought of ft basis transform, why introduce redundancy? thank you. the redundancy because input strictly real signal fft, dft result complex conjugate (hermitian) symmetric. redundancy due fact imaginary components of strictly real input zero. output of dft can include non-zero imaginary components indicate phase. thus, dft result has conjugate symmetric imaginary components in result cancel out between 2 dft result halves (same magnitudes, opposite phases), indicating strictly real input. also, lower 257 bins of basis transform have 512 degrees of (scaler)freedom, input. however, spectrogram throws away phase information, can display 257 unique values (magnitude-only). ...

i learning c++ while. make pointer class curiously recursive template pattern, following. unfortunately, did not work because default operator==() function of derived class hides operator==() function of base class. have smart way inhibit hiding operator function of base class 1 of derived class? or know way avoid issue? in case, append messages compiler. thank much. #include <vector> template <typename derived, typename t> class function0 { public: friend bool operator== (derived& org, derived& cmp) { // ***** line gives warning derived& org_value = static_cast<derived&>(org); derived& cmp_value = static_cast<derived&>(cmp); return *(org_value.value_) == *(cmp_value.value_); // *** old code: return org_value == cmp_value; } }; template <typename t, template <typename derived, typename t_t> class functions> class pointer : public functions<pointer<t,functions>, t> { publi...

i'm making small web application react, redux, , react-router-redux. when visit main page, can submit form triggers async redux action makes call service- fetching data, hydrating store response, , showing response based on new redux-reduced props. that works fine, there lack of routing url //mywebsite.com/ . the issue having want able navigate //mywebsite.com/view/[id] hydrate store props calling async redux action. i haven't been able find specifically... direction great.

working with: text on web page using tools: javascripts ones found here: http://www.tweakandtrick.com/2011/03/javascript-tricks-edit-websites-in.html , here: http://createjs.org/ current problem: when text edited, there no way save changes in order comeback after refresh or reopening page, , changes lost. question: possible somehow save changes made text of page, , not loose them after page refresh/reset? limitations: no access webpage being edited. the goal: open random page, make changes text using javascript above, saving steps in such way, apply them later same or pc opening same page , running script. this fundamental javascript, changes makes temporary, lasting whilst page loaded in browser. javascript has no access computer file system of server stored nor file system browser , such, can not modify or write self or computer, other in cookies . as mentioned, can use , store cookies in user browser remember state of thing written long cookie not deleted ...

i reading "learnyouahaskell" tutorial learnyouahaskell . there reads: pattern matching can used on tuples. if wanted make function takes 2 vectors in 2d space (that in form of pairs) , adds them together? add 2 vectors, add x components separately , y components separately. here's how have done if didn't know pattern matching: addvectors :: (num a) => (a, a) -> (a, a) -> (a, a) addvectors b = (fst + fst b, snd + snd b) well, works, there's better way it. let's modify function uses pattern matching. addvectors :: (num a) => (a, a) -> (a, a) -> (a, a) addvectors (x1, y1) (x2, y2) = (x1 + x2, y1 + y2) there go! better. note catch-all pattern. type of addvectors (in both cases) addvectors :: (num a) => (a, a) -> (a, a) - > (a, a) , guaranteed 2 pairs parameters. my question is: why pattern matching preferred preferred way, if both definitions result in same signature? i thin...

i need resolve problem using producer-consumer pattern using java , spring framework. problem new in spring framework (i have no idea) guide me in right direction how using spring? book or internet site can find example step step implementing producer-consumer pattern spring? you have 2 options: synchronous using applicationeventpublisher ( more ) asynchronous using spring reactor ( more )
