optimization - MATLAB Genetic Algorithm "Subscripted assignment dimension mismatch" Error -

-

when trying use genetic algorithm solver in matlab, i'm getting following "subscripted assignment dimension mismatch" error: error message pastebin

now, says error has fitness function @ end, when test fitness function separately, works without errors. can link code fitness , constraint functions if help.

thank much!

i think see happening... because 1 of appendages cdraft inside if, don't return same length vector - i.e., return constraint vector first time, preallocates matrix constraint output, next time round give doesn't fit in matrix, error.

the clue in error stack: @ top of stack have

subscripted assignment dimension mismatch.

error in c:\program files\matlab\r2012b\toolbox\globaloptim\globaloptim\private\gaminlppenaltyfcn.p>i_convectorizer (line 135)

clearly not function you've written, , inspecting function there's nothing should cause error. end of error gives clue

caused by: failure in initial user-supplied fitness function evaluation. ga cannot continue.

the ga function reporting error in bit of code handles user-supplied constraints. whole bit of code (the call user-supplied function , other associated lines) within 1 try...catch statement returns error. this:

try     c = userconfun(x);     if isempty(chistory)         chistory = zeros(length(c), 1000); % or whatever     end     chistory(:, currentiterationindex) = c; catch err     error('failure in user-supplied fitness function blah blah blah'); end

consequently, looks error came function, though occurred after function returned.

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;
