Hi, I am trying to display a multidimensional array into html table using php nd mysql. The array structure is like below Array ( [az] => Array ( [0] => Array ( [work] => dsdsds [time] => 2:47---2:55 [total] => 8 ) ...
I would like to create a list inside another list. How can I do this? And how do I retrieve values from the list which is inside another list? ...
let's say i have a multidimensional hash, and in one of the subhashes i have a key=>value pair which i need to retrieve by key. how can i do it? example hashes: h={:x=>1,:y=>2,:z=>{:a=>{:k=>"needle"}}} h={:k=>"needle"} key is always :k, and i need to get "needle" i noticed that there is no "flatten" function for hashes in ruby 1.8, ...
I want to create two and three dimensional vectors using a constructor in a class. However, I do not know how for multidimensional vectors. One dimensional works: class One{ public: vector < float > myvector; One(int length) : myvector(length){} }; Two dimensional does not work: class Two{ public: v...
I have several questions: 1. What's the difference between isoMDS and cmdscale? 2. May I use asymmetric matrix? 3. Is there any way to determine optimal number of dimensions (in result)? ...
I am trying to integrate a multivariable function in scipy over a 2d area. What would be the equivalent of the following Mathematica code? In[1]:= F[x_, y_] := Cos[x] + Cos[y] In[2]:= Integrate[F[x, y], {x, -\[Pi], \[Pi]}, {y, -\[Pi], \[Pi]}] Out[2]= 0 Looking at the scipy documentation I could only find support for one dimensional...
I'm working on a problem where i need to process multi dimensional data in memory using C#. My requirement resemble OLAP cubes but are not as complex. for example i don't need calculations or aggregation or stuff like that. I basically would like to reference data using multidimensional keys. for example: var key = new Key(); key["Dim1...
I have data in the form { {x,y,z,f}...} I am using ListContourPlot3D but all I get is an empty box with dimensions -1,1 in each direction. Here is my code: ListContourPlot3D[data5, PlotRange -> All, AxesLabel -> {"[Beta]", "[Omega]", "Vo"}, Contours -> {1500}]. These are the first 5 points of my data:( the whole set has 55 points) {{200,...
I have a vector of vectors: vector< vector<int> > BigVec; It contains an arbitrary number of vectors, each of an arbitrary size. I want to delete not duplicate elements of each vector, but any vectors that are the exact same as another. I don't need to preserve the order of the vectors so I can sort etc.. It should be a really simple...
For a game server, I want to record details when a player makes a kill, store this, and then at intervals update to a sql database. The part i'm interested in right now is the best method of storing the kill information. What i'd like to pass to the sql server on update would be {PlayerName, Kills, Deaths}, where the kills and deaths ar...
Eg :a=[["hello", "world"], ["good", "lord"], ["hello", "lord"]] I need to find and record the indexes of each word with respect to the super-array. i.e hello => 0,2 world => 0 lord => 1,2. here's my shot ,but its very amateurish and lengthy. all_tokens=tokens.flatten all_tokens.each do|keyword| ...
Input: two multidimensional (for example dim=8) vectors a and b. I need to find out the "directed" angle (0-2*Pi, not 0-Pi) between those vectors a and b. And if they are not parallel I need to rotate vector b in plane a,b by "directed" angle L. If they are parallel, plane does not matter, but angle of rotation is still the same L. For...
I've got an array that looks like this: Array ( [0] => Array ( num => 09989, dis => 20 ) [1] => Array ( num => 09989, dis => 10 ) [2] => Array ( num => 56676, dis => 15 ) [3] ...
I have an array which is converted from an XML response. What I need to do is sort the array ascending alphabetically using the 'COMPANY' value. I have attempted to use array_multisort, but I'm having no luck at all. Any help would be greatly appreciated. Here is the array: array(1) { ["DATASOURCE"]=> array(1) { ["MEMBER"]=> ...
I have the following code. $connect = new Connection (); $response = $connect->putFile($fileName, $destination); header("Location: /test.php?response=" . $response); When I invoke header with the response, the file will stop execution, but I will have no error in the console... I am thinking maybe this array needs to be encoded for ...
I'm trying to sort a multidimensional object, and, after looking on php.net and around here, I get that I should write a function that I can then call via usort. I'm having some trouble with the syntax. I haven't ever written something this complicated before, and trying to figure it out feels like a mindbender... I'm working with th...
Hello Everyone, Right now i got an array which has some sort of information and i need to create a table from it. e.g. Student{ [Address]{ [StreetAddress] =>"Some Street" [StreetName] => "Some Name" } [Marks1] => 100 [Marks2] => 50 } Now I want to create database table like whic...
I have a flat array that I'm trying to make multidimensional. Basically, I want to find the items that have parents and create a subarray for that parent id. Right now (and this is simplified), it looks like this: Array ( [0] => stdClass Object ( [id] => 1 [parent] => 0 [name ] => Parent1 ) [1] => stdClass Object...
How would you sort a multidimensional array in JavaScript? I have an array full of arrays that contain two dates and a string. I need the main array sorted by one of the date arrays, is this possible? data stucture: events = [ { date 1, date 2, string }, { date 2, date 2, string }, ] ...
I have a multidimensional array and am trying to group by a value of one the keys. So Array ( [0] => Array ( [name] => Edward Foo [desc_topic] => Array ( [0] => Apple [1] => Banana [2] => Orange ) [qt...
