What would be the best way to manage large number of instances of the same class in MATLAB? Using the naive way produces absymal results: classdef Request properties num=7; end methods function f=foo(this) f = this.num + 4; end end end >> a=[]; >> tic,for i=1:1000 a=[a Request];en...
I have this as Main int[] M ={ 10, 2, 30, 4, 50, 6, 7, 80 }; MyMath.Reverse(M); for (int i = 0; i < M.Length; i++) Console.WriteLine(M[i].ToString() + ", "); After I created the class MyMath I made the Reverse method public int Reverse(Array M) { int len = M.Length; for (int i = 0; i < len / 2; i++) { ...

I want to store a large result set from database in memory. Every record has variable length and access time must be as fast as arrays. What is the best way to implement this? I was thinking of keeping offsets in a separate table and storing all of the records consecutively? Is it odd? (Programming Language: Delphi) ...

I'm using nusoap to connect to a soap webservice. The xml that the class sends to the service is constructed from an array, ie: $params = array("param1" => "value1", "param2" => "value1"); $client->call('HelloWorld', $params, 'namespace', 'SOAPAction'); This works fine. A multidimensional array also constructs a nice nested xml messag...
This is related to some other questions, such as: this, and some of my other questions. In this question, and others, we see we can declare and initialise string arrays in one nice step, for example: const char* const list[] = {"zip", "zam", "bam"}; //from other question This can be done in the implementation of a function with no bo...
Is there a simple way to retrieve the length of an associative array (implemented as an Object) in ActionScript 3.0? I understand that there are two primary ways of creating associative arrays in AS3: Use a Dictionary object; especially handy when the key does not need to be a string Use an Object, and simply create properties for eac...
I have a file (called "number.txt") which I want to read to an array in Java. How exactly do I go ahead and do this? It is a straight-forward "1-dimensional" file, containing 100 numbers. The problem is that I get an exception every time. Apparently it can't find it (I am sure its spelled correctly). When looking through code examples, ...
example: I want to see if array[5] holds a value or is empty. ...
I want to build two-dimentional array of strings where length of one dimention is 2. Similar to this string[,] array = new string[,] { {"a", "b"}, {"c", "d"}, {"e", "f"}, {"g", "h"} } Doing List<string[]> list = new List<string[]>(); list.Add(new string[2] {"a", "b"}); list.Add(new string[2] {"c", "d"}); list.Add(new...

I am trying to covert the a date format into another format, but i need to string to the arrays. $datetochange="2008-11-5"; $date_parts=explode("-", $datetochange); //Displays 2008 print $date_parts[0]; //Displays 11 print $date_parts[1]; //Displays 5 print $da...
I am working on refactoring some old code and have found few structs containing zero length arrays (below). Warnings depressed by pragma, of course, but I've failed to create by "new" structures containing such structures (error 2233). Array 'byData' used as pointer, but why not to use pointer instead? or array of length 1? And of course...
In javascript, I've got a block of HTML like this: <h2>{title}</h2> <p><a href="{url}">{content}</a></p> And I'm trying use regex "match" to spit out an array of all the {item}'s.
