this question has answer here: how abort running program in matlab? 1 answer i write long running script in matlab, e.g. tic; d = rand(5000); [a,b,c] = svd(d); toc; it seems running forever. becasue press f5 in editor window. cannot press c-break stop in matlab console. i want know how stop script. current use task manager kill matlab, silly. thanks. matlab says this- m-files run long time, or call built-ins or mex-files run long time, ctrl+c not stop execution. typically, happens on microsoft windows platforms rather unix[1] platforms. if experience problem, can matlab break execution including drawnow, pause, or getframe function in m-file, example, within large loop. note ctrl+c might less responsive if started matlab -nodesktop option. so don't think option exist. happens many matlab functions complex. either have wait or don't use the...

i'm curious. why asp.net listitem class need sealed? back read interview 1 of creators of bcl, think scottgu. iirc said similar "for classes, regretted made them sealed, , other classes regretted did not make them sealed". so assumption design desicion may not transparent bcl users. on other hand, 100k+ user knows more internals it.

i have program deal lot of small numbers (towards lower end of double limits). during execution of application, of these numbers progressively smaller meaning "estimation" less accurate. my solution @ moment scaling them before calculations , scaling them down again? ...but it's got me thinking, gaining more "accuracy" doing this? thoughts? are numbers really in region between 10^-308 (smallest normalized double) , 10^-324 (smallest representable double, denormalized i.e. losing precision)? if so, scaling them indeed gain accuracy working around limits of exponent range of double type. i have wonder though: kind of application deals numbers extremely small? know of no physical discipline needs that.

i'm trying write regular expression match line: dd month year @ hh:mm example: 21 may 2009 @ 19:09 so have: [0-30-9] day [0-20-90-90-9] year [0-90-9:0-90-9] time i don't understand how put these form 1 single regex. want do if($string =~ /myregex/) { } but can't form entire thing. don't know how write regex month, has match 1 of 12 months of year. i perl noob (this first day) , regex noob, appreciated! well, parts have aren't quite correct. instead of [0-30-9] think mean [0-3][0-9] , , other numbers. however, suffices little looser , use \d equivalent [0-9] . you string parts 1 after other: /\d\d (month) \d\d\d\d @ \d\d:\d\d/ which can written more succinctly as: /\d\d (month) \d{4} @ \d\d:\d\d/ or if need more strict in formulation: /[0-3]\d (month) [0-2]\d{3} @ \d\d:\d\d/ i've left month bit last, since more complicated bit. again can loose or strict. loosely: /[0-3]\d [a-za-z]+ [0-2]\d{3} @ \d\d:\d\d/ for s...

hi stackoverflower, use eclipse helios , problem. i have main project name main . dynamic web project. have util project name util . simple java project. i open deployment assembly main project. click add -> project -> choose util project-> finish in screen show new project in table source : util | deploy path : /web-inf/lib/util.jar anything good, click ok. when go deployment assembly again util project disappear. , sure when deploy, util project doesn't become jar file library. thanks suggestion. to echo comments above, took notice of bug 318068 "aggregate deployment assembly fixes helios sr1 ", includes a lot bug fixes regarding feature. the op diewland reports: it works! update eclipse , ok. so eclipse3.6.1 recommended "deployment assembly" operations.

i implementing image filtering operation in c using multiple threads , making optimized possible. have 1 question though: if memory accessed thread-0, , concurrently if same memory accessed thread-1, cache ? question stems possibility these 2 threads running 2 different cores of cpu. way of putting is: cores share same common cache memory ? suppose have memory layout following int output[100]; assume there 2 cpu cores , hence spawn 2 threads work concurrently. 1 scheme divide memory 2 chunks, 0-49 , 50-99 , let each thread work on each chunk. way let thread-0 work on indices, 0 2 4 , on.. while other thread work on odd indices 1 3 5 .... later technique easier implement (specially 3d data) not sure if use cache efficiently way. in general bad idea share overlapping memory regions if 1 thread processes 0,2,4... , other processes 1,3,5... although architectures may support this, architectures not, , can not specify on machines code run on. os free assign code core like...

i have learned connection interface , can define method definition in interface. how work: .... statement stmt = con.createstatement(); .... how method create statement object , return it? because concrete implementation of connection interface been returned when called getconnection() . interface definies method signatures. concrete implementation contains method implementations. connection connection = drivermanager.getconnection(url, username, password); system.out.println(connection.getclass().getname()); // that's name of concrete implementation. it's jdbc driver contains concrete implementations. jdbc api enables write java code independent of specific database server used. whenever switch of db, have switch jdbc driver (and possibly change sql statements whenever contain db-server specific sql language, not java code).
