matlab - Normrnd Function generating same random numbers -

-

is possible normrnd function of matlab generates same set of random numbers on 2 different machines (when no seed has been set)?

it may if both generators seeded same way on both machine (ex. launched @ same time, , seeded current time). actually, mentionned in comment, seeding in matlab not current time, same @ launch if not seeded.

  • if wish reproduce same series of random numbers, may take @ example: can save current seed , reuse later.

save current generator settings in s:

> s = rng; call rand generate vector of random values:  > x = rand(1,5)  > x =      0.8147    0.9058    0.1270    0.9134    0.6324

restore original generator settings calling rng. generate new set of random values , verify x , y equal:

> rng(s); y = rand(1,5)  > y =        0.8147    0.9058    0.1270    0.9134    0.6324

  • matlab gives possibility choose generator. choosing pseudo random number generator mersenne twister, , seeding same seed @ each run, same series.

  • if wish have different series of randm numbers @ each run, can use rng('shuffle'), seeding generator clock time @ start.

Perl - how to grep a block of text from a file -

it can in xml or text format. how in general grep block of text in perl? <track type="ws"> <range> <rangestart>0</rangestart> <rangeend>146.912</rangeend> <locationindex>0</locationindex> <propertyindex>0</propertyindex> </range> </track> <track type="ps" id="1"> <range> <rangestart>0</rangestart> <rangeend>146.912</rangeend> <locationindex>1</locationindex> <propertyindex>1</propertyindex> </range> </track> i want grep type="ps" , till </range> . one solution open file, read line line , match block. open(fh, "file.txt"); foreach $line (<fh>) { if ($line =~ m/type="cc"(.*?)<\/range>/) { print $1; } } but there more optimal solution without reading file line l

delphi - How to remove all the grips on a coolbar if I have several coolbands? -

-
Image
if set mycoolbar.fixedorder true,only grip on first band hidden. well,if use delphi 7 create vcl forms application,then put coolbar on , create 3 coolbans hold other controls,only grip , top coolbands can hidden setting mycoolbar.fixedorder:=true. i've uploaded picture make things clear. you got fixedorder property wrong. fixed property not allow bands rearranged if set true . setting property of coolbar true keep user changing bands order @ runtime, user can still move , resize bands. can give advice can do, actual solution problem, well, have wait answer. my advice use 3 coolbars in row , setting "fixedorder" property true , bandborderstyle bsnone . way grip hidden on of them. about property, it's not bug of ide, actual preference of property.

javascript - Animating array of divs; only the final element is modified -

this baffling me @ moment. i'm experienced programmer looking throw bit of surprise fiancee on countdown page our wedding. desired effect simulated confetti falling behind main page. setup follows: i have array of divs in javascript. each div absolutely positioned on page. have interval set updates every 50 or milliseconds. on each tick, run loop on array of divs, , calculations , update positions. problem problem having, however, though can see divs created, stored array, , modified (in case, each has slight randomized rotation) during initialization phase, once tick update position starts, div stored in whatever last slot of array gets position updated. tried hard-coding each div index testing purposes, strictly last element update position. upon printing current "left" , "top" style values each div before , after calculations shows value has been changed, no visible change noticeable. here's basic code: javascript var container;
