Implementing custom MATLAB functions in Simulink -

-

i use custom matlab function in simulink. far have done placing embedded matlab function block. however, if custom function contains custom function compile process fails.

here example of function trying embed in simulation:

function [c, d, iterationscount] = decodeldpc(y, h, variance) lci = initializelq(y, h, variance); lr = getlr(lci); [lq, c] = getlq(lci, h, lr); iterationscount = 1;  while(sum(mod(c * h', 2)) ~= 0)     lr = getlr(lq);     [lq, c] = getlq(lq, h, lr);     iterationscount = iterationscount + 1; end; g = getgeneratormatrix(h); d = c/g;

where initializelq , getlr custom functions well.

is there method implement above function in simulation?

you need use command eml.extrinsic call external matlab functions eml block. example, can put @ top of eml function,

eml.extrinsic('getlr', 'initializelq');

to allow functions called. more information, see documentation

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
