i experiencing problem , guys might of me. in matlab, trying solve implicit function, see following: cp = cpi / ( sqrt(1 - m^2) + (m^2 / (sqrt(1-m^2))) * cpi/2 ) here, know values of both m , cp , want know value of cpi. also, due computational time considerations, avoid using loops in approach. finally, know not hard solve, example 1 can use ''golden bi-section'' method find answer, not know how code in matlab. know, or has piece of code able solve cpi? thank guys! appreciated help this quite done using fzero . if move cp part on rhs, , try find root using fzero , cpi variable, can solve this: m = 0.4; cp = 3; f = @(cpi) cp - (cpi / ( sqrt(1 - m^2) + (m^2 / (sqrt(1-m^2))) * cpi/2 )); fzero(f,0) ans = 3.7250 of course, don't need assign anonymous function first, in opinion, makes easier read.

i have snippet make page refresh every minute. however, want page fade out specific color, refresh , fade in again. easy way that? this code use; setinterval("refresh();",60000); function refresh(){ window.location = location.href; } i found code while searching solution, unsure on how can use in interval; $("body").fadeout( function(){ location.reload(true); $( document).ready( function(){$(body).fadein();}); }); demo add css hide body on page load. body{display:none}; then on load, fade body in. after 60 seconds fade out, trigger page reload putting inside callback executes after fadeout finishes. $(function(){ $('body').fadein(1000); settimeout(function(){ $('body').fadeout(1000, function(){ location.reload(true); }); }, 60000); }); no need use setinterval page gets reloaded; settimeout fine.

i have bunch of hex numbers, don't feel doing qbytearray ba; ba.append(0x01); ba.append(0x02); ba.append(0x7a); ... can in 1 line? maybe qstring manipulation? i'm sending messages via serial communication qextserialport , need store hex commands in qbytearray can use qint64 write(const qbytearray &data) the first point is: there no such thing hex numbers. numbers numbers. we're talking of integers here. whether 16, 0x10, 020, etc., it's same number. 0x10 "hex" in sense write out in hexadecimal notation. doesn't change number itself, doesn't make "hex"! it's still number incrementing 0 sixteen times. the reason hexadecimal device's documentation gives command packets in hexadecimal. it's arbitrary choice. can copy numbers in hexadecimal documentation, or convert them base if makes more sense you. so, hexadecimal representation of course you, don't need explicitly use it. need use c constant arrays i...

is there way access variables outside class? class myclass1 { public: int x; }; class myclass2 { public: int get_x() { //somehow access myclass1's variable x without //passing argument , return it. } } int main() { myclass1 obj1; obj1.x = 5; myclass2 obj2; std::cout << obj2.get_x(); return 0; } one of main things making me reluctant split programs many small organized classes rather few messy huge ones hassle of passing every single variable 1 class might need another. being able access variables without having pass them (and having update both declarations , definitions should change) convenient , let me code more modually. any other solutions issue appreciated, suspect there may dangerous trying access variable way. the way can access x of myclass1 if have instance of class, because x not static . class myclass2 { public: myclass2(myclass1* c1) : myc1(c1) {} int get_x() { retu...

the following sequence diagram models initialisation of ftp server, uses couple of factories ( ftpserverfactory , listenerfactory ) create required objects. unfortunately said interactions increase complexity of diagram without adding useful insight. i have drawn sequence diagram omitting these factories, , in opinion looks more clear. i wonder if it's possible replace <<create>> stereotype (say) <<factory>> stereotype point out objects instantiated factories. also, i'm bit dubious reply messages, if necessary show them or not. thanks you have freedom so. serves communicating thoughts fine. should in such cases add comment (if have no common document/glossary it) place note on diagram explaining use of <<factory>> stereotype.
