i know cell array is. came following line: cell_array = cell([], 1); what mean? how can read above line? thanks. so makes 0x1 empty cell array. in literally 0 rows , 1 column. make 0x0 cell array this: cell_array = {} which makes sense me. if can't preallocate before loop, it's useful concatenate onto or go cell_array(end) = ... in loop. i don't know why you'd prefer 0x1 this question shows how differs 0x0. mean, if weird reason running loop on empty array know run @ least once :/ that's scraping barrel reason. think stick = {} . edit: as @radarhead points out, 1 way preset number of columns if plan on concatenating new rows in loop.

i running query find out total amount of time user has been browsing for. each browsing session stored in db seconds , sum total seconds , convert hh:mm:ss. problem when i'm converting seconds hh:mm:ss . want display example '78:20:00' dont know how code total this. when gets past 24 hrs hrs column goes 00 because day. the query run convert time can seen below: select username, convert(varchar(12),dateadd(second,totaltimeinseconds,0),108) totalhours #totalsessiontime select username, cast(totaltimeinseconds / (60 * 60) varchar) + ':' + cast(totaltimeinseconds % (60 * 60) / 60 varchar) + ':' + cast(totaltimeinseconds % (60) varchar) totalhours #totalsessiontime if want minutes , seconds 2 digits, you'll have left pad them, make ugly example, work fine.

i'm trying x-coordinates of peaks in matlab figure (example attached). i've been using findpeaks , doesn't seem fact i'm plotting points rather lines. i won't have 2 peaks. i'll have three, i'll have one. multiple peaks separated @ least 1/4 of range of x, , peaks @ least twice noise level. here's expect work: [pks,locs] = findpeaks(ydata,... 'sortstr','descend',... 'minpeakdistance',floor(range(xdata)/4),... 'minpeakheight',floor(max(ydata)/2)... ) instead of getting 2 peaks, 4 bundled around first peak: >> locs locs = 6774 166785 326792 486799 >> xdata(locs) ans = -96780.787939025 -96770.1800919265 -96770.8959353367 -96771.6117787468 i assume minpeakdistance working on in xdata indices rather data itself. how use distances between peaks instead of distance betwe...

how can adjust fairness between given k threads generate output? in other words imagine have k threads printing "1" , n threads printing "2". how can put fairness between threads each thread print(for example "1") as other (k - 1) print(for example "1").and same n thread printing "2". before create threads, create array[0..numthreads-1] of empty semaphores, 1 each thread going create. signal each thread on creation incrementing semaphore index, 0..numthreads-1. in thread function, have wait on semaphore[index], print something, signal [(index+1) mod numthreads] semaphore, loop round wait on semaphore[index] again. once have done that, nothing should happen @ all. throw in 1 semaphore unit, anywhere.

just hour ago, started tailing apache log file (access logs), , since then, ve noticed weird user agent, (couldnt find google's official docs). i m feeling suspicious it, since couldnt find on google's site user agent, ("mozilla/5.0 (compatible; googleapps script; +http://script.google.com/bot.html)) it has crawling login page of our site, every minute, whole day. here's log snippet: 72.14.199.55 - - [07/aug/2013:16:06:28 +0000] "get / http/1.1" 302 639 "-" "mozilla/5.0 (compatible; googleapps script; +http://script.google.com/bot.html)" 72.14.199.55 - - [07/aug/2013:16:06:28 +0000] "get /accounts/login/ http/1.1" 200 3780 "-" "mozilla/5.0 (compatible; googleapps script; +http://script.google.com/bot.html)" and has been same ip. , still is, is common see pattern of crawling? google apps scripts allow users write javascript based code , set them run @ specified intervals google'...

i have quick question, should relatively simple have more experience in wmi-command processor (and since i'm absolute beginner thats not hard :-) ) i fail understand why wmic /format switch works way does. open cmd.exe , type wmic process list brief /format:htable > processlist.html this want , no bothers further on. whereas if go wmic processor, , try execute same command above... wmic:root\cli>process list brief /format:htable > processlist.html i receive error tag: "invalid xsl format (or) file name." here goes screenshot. note have copied xsl files wbem sys32 dir can explain me why these 2 commands me same, difference 1 executed outside wmic environment , other 1 inside, latter 1 doesn't work? fail understand it. please advise can comprehend bit better! :-) you attempting use cmd.exe > redirection while within interactive wmic context. can't work. you can use wmic /output:filename switch while in interactive mode....

considering new cpus new instructions moving , new memory controllers, if in c++ have vector of derived objects derived composed of virtual member functions, or bad thing locality ? and if have vector of pointers base class base* store references derived objects 1-2-3 level base ? basically dynamic typing applies both cases, 1 better caching , memory access ? i have preference between 2 see complete answer on subject. there new consider ground-braking hardware industry in last 2-3 years ? storing derived rather base * in vector better because eliminates 1 level of indirection , have objects laid out «together» in continuous memory, in turn makes life easier hardware prefetcher, helps paging, tlb misses, etc. however, if this, make sure don't introduce slicing problem. as virtual dispatch in case, not matter exception of adjustment required «this» pointer. example, if derived overrides virtual function calling , have pointer devied * , «this» adjustmen...

i using barby , png outputter. have gotten compile fine, not sure how can display image. here code.. controller: @barcode = barby::code128b.new(@num) @blob = barby::pngoutputter.new(@barcode).to_png #raw png data file.open('barcode.png', 'w'){|f| f.write @blob } application helper: require 'barby' require 'barby/barcode/code_128' require 'barby/outputter/png_outputter' view: <%= @blob %> since @blob image data, can't "print" regular string. need use image_tag instead, , give path image. like: <%= image_tag("barcode.png") %>

i need create number of arrays of object number need dependent on separate variable best way explain psudo code example: int num = 4; for(int i=0;i<num;i++){ object_type arrayi [dynamic size]; } so need 4 arrays each names array0,array1,array2, , array3 , must dynamic arrays. there anyway in c++? std::array<std::vector<object_type>, 4> array; (auto & v : array) v.resize(dynamic_size); the names array[0] , array[1] , etc... instead of array1 , array2 , etc... cares? if absolutely must have names, cassio's answer best bet. pre c++11 alternative: std::vector<object_type> array[4]; (size_t i=0; i<4; ++i) array[i].resize(dynamic_size); if want variable number of arrays, can use vector of vectors, , actually, initialization easier. doesn't require loop, can in constructor. std::vector<std::vector<object_type>> array(num, std::vector<object_type>(dynamic_size));

long story short, i've been working on project , noticed when use: 1.9.3p392 :001 > `gzip` irb::abort: abort interrupt!
