what's efficient way populate cell array values vector (each formatted differently). for example: v = [12.3 .004 3 4.222]; desired cell array: array = {'a = 12.30' 'b = 0.004' 'c = 3' 'd = 4'}; is there easier way calling sprintf each , every cell? array = {sprintf('a = %.2f',v(1)) sprintf('b = %.3f',v(2)) ... } there's no vectorized form of sprintf supports different formats, you're stuck sprintf call per cell. arrange code easier deal in loop. v = [12.3 .004 3 4.222]; names = num2cell('a':'z'); formats = { '%.2f' '%.3f' '%d' '%.0f' }; c = cell(size(v)); = numel(v) c{i} = sprintf(['%s = ' formats{i}], names{i}, v(i)); end it tricky faster naive way without dropping down java or c, because it's still going take sprintf() call each cell, , that's going dominate execution time. if have large number of elements , relatively sma...

[first time on stackoverflow.] trying dynamically add html buttons page , give them javascript function run when clicked, using jquery's click. want have 1 button each element in array, used loop. code looks (simplified) for (var = 0; < results.length; i++) { $("#" + place[i].place_id).click(function(){console.log("test");}) $("#" + place[i].place_id).click(); } (i inject buttons right id's in same loop.) code, when run, console logs "test" right number of times, afterwards, last button responds "test" when clicked. (this situation little absurd.) so, think event handler ends using final value of assign event handler. think problem has closures, not sure how make closure out of jquery selector (and in general not familiar them). in contrast, hack solution, "manually" wrote code below right below , outside loop, , works expected, in clicking causes console log. $("#" + place[0].p...

i'm trying send model created using javascript (because created manually user) mvc controller. the model quite complex , 1 class uses double? type variable. works fine int numbers when use "0.5" value set null. what reason why double value fail , can it? some code: var serie = {}; serie.name = $(elem).children("#name").val(); serie.unitmeasurement = $(elem).children("#unitmeasurement").val(); serie.thresholdred = $(elem).children("#redthreshold").val(); serie.thresholdyellow = $(elem).children("#yellowthreshold").val(); public class serie { public string name { get; set; } public string unitmeasurement { get; set; } public double? thresholdred { get; set; } public double? thresholdyellow { get; set; } } you can use class like- public class serie { public string name { get; set; } public string unitmeasurement { get; set; } pub...

after trail , error i'd share issue dealing with. i'm populating struct , convert xml ( xml.marshal ) can see below foo example works expected. bar example creates empty group1. so question : "how prevent group1 generated if there no children set." package main import ( "fmt" "encoding/xml" ) type example1 struct{ xmlname xml.name `xml:"example1"` element1 string `xml:"group1>element1,omitempty"` element2 string `xml:"group1>element2,omitempty"` element3 string `xml:"group2>example3,omitempty"` } func main() { foo := &example1{} foo.element1 = "value1" foo.element2 = "value2" foo.element3 = "value3" fooout, _ := xml.marshal(foo) fmt.println( string(fooout) ) bar := &example1{} bar.element3 = "value3" barout, _ := xml.marshal(bar) fmt.println( string(barout) ) } ...

in application,i have long green grass bitmap.i have fix bitmap not move bottom part , should placed @ left bottom corner of screen.so have fix pivot @ bottom center of bitmap.after should move bitmap (like grass moving wind) left,some pixels , right,some pixels distance.but bitmap should not move pivot position.i unable fix pivot position , achieve grass moving.i posting code have done.please me solve this. private float direction = 1; private float mangle = 0; bitmap green_1 = bitmapfactory.decoderesource(getresources(), r.drawable.green_1); private void drawpaper(canvas canvas){ paint paint=new paint(); paint.setantialias(true); paint.setfilterbitmap(true); if (mangle >= 3) { direction=-0.2f; } else if (mangle<=-3) { direction=0.2f; } mangle = mangle + direction; matrix matrix = new matrix(); matrix.posttranslate(0,heightofcanvas...
