i working, matlab, on 3d simulator aim move object (currently it's simple circle) in space (using plot3). although it's easy compute trajectory without rotation of object, not manage rotate object around own axis. indeed, have computed 3 well-known rotation matrix (of course) rotate object (represented set of points) around axis of figure (in "world" system). for example, center of inertia of object (currently center of circle) coordinates (xi,yi,zi). thus, suppose need define additional system object able rotate object these 3 new axis composing such system... i like: [x2,y2,z2]=mat*[x1,y1,z1] [x1,y1,z1] coordinates of point of object before rotation, [x2,y2,z2] coordinates after rotation , mat matrix looking for. of course, center of inertia must unchanged whichever rotation (yaw and/or pitch or/and roll) however have no idea way compute such matrix. link below summarizes wish. drawing of problem

i new c++ , object oriented programming in general. objective use void pointer point fstream object. have structure contains void pointer. want use pointer reference fstream object can use in other functions write file using protocol buffer apis (serializetocodedstream).i want able write same file through repeated function calls (and read it). way i'm using protocol buffers serialize data , write file. my structure is: typedef struct store { void *obj; } st; my code create fstream object , use pointer point object st *entry1; fstream output; output.open("file1.txt", ios::out | ios::trunc | ios::binary); entry1->obj=&output; this i'm using pointer int addtofile( st *entry) { ostreamoutputstream *_ostreamoutputstream; codedoutputstream *_codedoutputstream; _ostreamoutputstream = new ostreamoutputstream(entry->obj); _codedoutputstream = new codedoutputstream(_ostreamoutputstream);

is there way implement this? http://i.imgur.com/jbhambk.gif have tried using ttattributedlabel no success (no flashing , time doesn't change anymore). does know of way make happen? any appreciated thanks everyone matt you can use timer. - (nstimer*)createtimer { // create timer on run loop return [nstimer scheduledtimerwithtimeinterval:1.0 target:self selector:@selector(timerticked:) userinfo:nil repeats:yes]; } - (void)timerticked:(nstimer*)timer { [yourlabel settext:@""] … } - (void)actionstop:(id)sender { // stop timer [mytimer invalidate]; }

in below diagram, have query on name temp returned function f in local frame f , temp reference variable pointing object 6 of class int , when return temp in f reference variable output part of checkpassingmech frame point same object 6 temp pointing to. my question: q1) understanding correct? q2) if q1 yes, diagram giving illusion temp not reference type , showing value in box rather arrow pointing 6, correct? q3) if q2 yes, then, can 6 stored in heap , temp , output pointing heap space frame(local stack) >>> def f(): temp = 6 print(id(temp)) return temp >>> output = f() 507107408 >>> id(output) 507107408 from doc : cpython implementation detail: cpython, id(x) memory address x stored. so strictly speaking, if value 6 , output , temp pointing same object, int object cached when python started. you may refer identifying objects, why returned value id(...) change? more information.

i have backed out commit (commit#1), after realized needed commit. have checked out commit#1. now, how can put version end of branch? if haven't done other work, can reset current branch on commit. git checkout yourbranch git reset --hard <sha1> the op barnabas szabolcs advices in comments: git reset --soft @^ (with recent git, @ alias head) that allow keep working tree , index (of checked out old commit) intact, while resetting head previous commit in order make new 1 (with content of checked out commit). if have done other commits, need cherry-pick commit current branch: git checkout yourbranch git cherry-pick <sha1> in case, checkout of old commit dangerous, leads detached head situation (except when followed git reset ---soft head^ ).

is auto command in c++11 static binding(typing) or dynamic binding? i.e. if have code auto x = 5; will compiler decide "x" int, or descovered on runtime? also, type of x in following code? auto x = 5, y = 4.5 this called type inference . typing still static , leave compiler figure out type of expression is. specifically auto x = 5; , @ compiler time, is translated int x = 5; . reason have provide unambiguous expression @ initialization. example auto x; wouldn't work .

in e-commerce site, have configured fedex shipping shipping api. in methods, i've choose 1 allow method "international economy". though have 1 method allow, checking logs of fedex, seems api query methods , return result. because of this, took @ least minute return shipping rates. is normal magento? or there anyway speed query speed or there modification or hack can make query allow method? kindly advise. thank you. i have seen few questions fedex magento , speed recently. i not convinced fedex request causing delay, figure out (and answer questions):- the code sends out requests is: //file: app/code/core/mage/usa/modell/shipping/carrier/fedex.php //class: mage_usa_model_shipping_carrier_fedex //function: _getquotes() protected function _getquotes() { $this->_result = mage::getmodel('shipping/rate_result'); // make separate request smart post method $allowedmethods = explode(',', $this->getconf

i want compare 2 different widths of floating-point numbers giving assert z3. example, want compare between ieee 32-bit , ieee 64-bit floating-point number. my try shown follows: (set-logic qf_fpa) (set-option :produce-models true) (declare-fun x_64 () (_ fp 11 53)) (declare-fun x_32 () (_ fp 8 24)) (assert (== ((_ asfloat 11 53) roundnearesttiestoeven x_64 ) x_64)) (check-sat) but got error message: (error "line 5 column 59: sort mismatch") what correct way compare 32-bit , 64-bit number? the z3 version using 4.3.1 (linux version). in general, these conversions non-trivial, e.g., when converting 64-bit down 32-bit precision may lost. why conversion functions take rounding mode. smt standard floating-point numbers contain conversion functions of following type: ; floating point sort ((_ to_fp eb sb) roundingmode (_ floatingpoint m n) (_ floatingpoint eb sb)) so, correct way convert between floating-point numbers use to_fp function.

i new fortran 95 , trying grip on nested loops. below small code nested loop. inner loop secant method calculates root of function "z+x1**2-612" , saves x0 via iteration. istep howmany iterations took. loop on own works. want repeat loop various "z". example 300 360 increments of 10. if run code, z vary 300 360 should, keep getting x0 300 (i.e. square root of 312). is there has experience nested loops (not secant method, since inner loop works), can tell me why print out 300 360 well, x0 if z never changes 300? browsed through forum, , found similar issues had variable declarations placed wrongly, doesn't seem problem in case. hereunder code, hope can me. bit old start learn programming, never late guess! program doloop2 implicit none integer :: istep,z real :: a,b,dl,dx,x0,x1,d,x2 dl = 1.0e-06 = 10 !lower guess b = 20 !upper guess dx = (b-a)/10.0 !stepsize x0 = (a+b)/2.0 istep = 0 !first iteration x1 = x0+dx z=300,360,10 wh

this graph definition of few terms horizontal glyph metrics fonts . let's have sentence, foo bar baz. how spacing size, in pixels, between words "foo" , "bar"? suppose sum, the whitespace right-padding in grapheme 'o' in "foo": subtract advance bearingx + width the advance of space character. the whitespace left-padding of letter 'b' in "bar": bearingx . is correct? table has bearingx? how spacing size, in pixels, between words "foo" , "bar"? you need know horizontal advance of space character , kerning between "o" , " ", , between " " , b". don't think need bearingx spacing. result in font "units", defined unitsperem of head tag. convert result * font size / unitsperem, , spacing in "points". need known, how many pixels there in 1 point: depends on application, monitor dpi or postscript's 72 dpi.

in our springmvc based website, want use litedevicedelegatingviewresolver . we have couple of other viewresolvers configured , want litedevicedelegatingviewresolver take precedence on those. however litedevicedelegatingviewresolver not implement ordered interface, hence cannot set order value on it. seems spring uses these values chain viewresolvers. there way make litedevicedelegatingviewresolver take precedence on other viewresolvers have configured? thanks.
