i new matlab , simulating physical phenomena requires physical coordinates of image. example can use following give dimensions of image. a = phantom(80,250) a(81:250,:) = []; for physical system, need spacing 2 between each pixel , object go 0:2:280 in x , 0:2:410 in y. trying use meshgrid see if case starting [x,y] = meshgrid(1:1:100, 1:1:300); [xm,ym] = meshgrid(1:.5:300, 1:.5:450); m = interp2(x,y,a,xm,ym,'nearest'); this not give me want how think can potentially achieve solution. my basic problem have image size (80,250) , need sample/scale can correlate point on top right location (280mm,410mm) sample of 2mm between each pixel. right approach or should use function? first of all, image not 80 x 250. sure go checkout documentation . what hoping after step? determines whether appropriate way go this. but based on code , last statement, want x range 0 - 280 , y range 0 - 410. xrange = linspace(0, 280, size(a, 2)); yrange = linspace(0, 410, siz

briefly: what's sourcetree equivalent of: git show 946a759:file.h more thorougly: file.h did not change in commit 946a759, want see contents of file @ time of commit. i know could change log view - working copy view show all of files, find file in list, right-click on , choose "log selected", find commit (or next oldest one) but that's cumbersome process i don't want change log view's setup show files it's difficult find random file in huge long list of files. so i'd in log view master branch selected in left sidebar, find particular commit in tree, , equivalent of git show rev:anyfileiwant. i'd fine typing in path file. i can't seem find way this?

i want concatenate strings variables if variables not nil. if nil, don't want include them. following code works clunky , grows proportionately more complex additional variables. can recommend more elegant way this? nsstring *city = self.address.city== nil ? @"" : self.address.city; nsstring *state = self.address.state== nil ? @"" : self.address.state; nsstring *zip = self.address.zip== nil ? @"" : self.address.zip; nsstring *bestcity; if (city.length>0&&state.length>0&&zip.length>0) { bestcity = [nsstring stringwithformat: @"%@ %@ %@", city, state,zip]; } else if (city.length>0&&state.length>0) { bestname = [nsstring stringwithformat: @"%@ %@", city,state]; } else if (city.length>0&&zip.length>0) { bestcity = [nsstring stringwithformat: @"%@ %@", city,zip]; } else if (city.length>0&&zip.length>0) { bestcity = [nsstring stringwithf

this question has answer here: does capacity of arraylist decrease when remove elements? 6 answers for add() method, implementation such elementdata\[\] array's size grows needed. however, looking @ remove() method, not shrink size elements removed. i tested using simple code , elementdata[] starts out 10 , grows. however, when delete elements using remove() method, size of elementdata[] stays @ point finished adding elements. int testsize = 10000000; arraylist<integer> alist = new arraylist<integer>(); // size of elementdata[] 10 for(int = 0; < testsize; i++) { alist.add(i); } // size of elementdata[] 13845150 for(int = alist.size()-1; >= 0; i--) { alist.remove(i); } // size of elementdata[] remains @ 13845150 isn't wasting memory? first should note size of array cannot changed, once created. changing size of

i confused why simple ruby object not converting json. >irb > require 'json' class user attr_accessor :name, :age def initialize(name, age) @name = name @age = age end end u1 = user.new("a", 1) u2 = user.new("b", 2) puts u1.to_json "\"#<user:0x000001010e9f78>\"" what missing? i want store these objects array collection, , convert entire collection json. users = [] users << user.new("a", 1) users << user.new("b", 2) users.to_json note: not using rails, plain old ruby! i want json array of user objects. [ {"name": "john", "age": 22}, {"name": "john1", "age": 23} {"name": "john2", "age": 24} ] by default, classes cannot made json strings. must have to_json method in class, can make inherit class (type class user < jsonable ): class jsonable def to_json

i'm trying create macro populate worksheet's row headers labeling them box numbers like: box 1 box 2 box 3 ... , on. the number of boxes in sheet. if number written there 8, possible populate other sheet's rows box 1 box 8? am making sense? thanks. if need fancier asked for, may need resort vba. if not, following works: create new excel file 2 sheets. on 2nd worksheet, in cell a1, enter number 10 on 1st worksheet, in cell a1, enter formula: =if(column()<=sheet2!$a$1,"box " & column(), "") on 1st worksheet, select a1. press ctrl-shft-right (this select entire row) press ctrl-r (this fill formula right) this works because column() returns current column number (a1, a2, a3 return 3. b1, b2, b3 return 2). a simple comparison between value in sheet2 , current column() value gives 1, 2, 3... whatever entered sheet2.
