I have the following Matlab function:
function [res] = a3_funct(x)
res = 0;
for i = 1:size(x,1)
res = res + abs(x(i))^i;
end
end
It's emulating this equation:
Here is an example use:
>> a3_funct([1,2,3]')
ans =
32
I know I should be able to use the sum() function...
I'm writing a php function to collect data from different positions in an given array, I've done it as follows which gives me what I require.
for ($a=9; $a < 13; $a++) {
$n = $arr[$a][2];
$p = $arr[$a][3];
$c = $p;
$v1[] = array($n,$p,$c);
}
for ($b=3; $b < 16; $b+=4) {
$h...
After reconstructing your example and playing around, i figured out what happens.
var data = await client.GetAsync(new Uri("https://mytestdomain/v2/apikey?format=Json"));
The GetAsync method invokes the http request with invalid credentials. What happens is that the returned request tries to l...
As your code has already been reviewed, I would just like to propose another solution: to find the longest common "substring" of the array and its reversal.
Finding this by dynamic programming can be done in \$O(n^2)\$ time and \$O(n)\$ space.
Hi there fellow coders,
I am looking to improve the following query.
We are using EF6 (CodeFirst) and C# Lambda Expressions, and Repository/Unit of Work patterns. Also, we needed to restrict the query in a way that we could inner-query the entities so that the query will only retrieve a subset...
Is it possible for my service to make a quiet phone call?
No.
I have been trying to implement a MPSC circular buffer in C for Linux.
Here it is the buffer structure:
typedef struct mpsc_buffer_s {
sem_t semaphore;
unsigned char cache_pad_1[CACHE_LINE - sizeof(sem_t)];
uint64_t write_pos;
unsigned char cache_pad_2[CACHE_LINE - sizeof(uint64_...
Just a small little comment about your array initializer:
int[][] matrix = {{0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 1,
0, 0, 0, 0, 0, 0, 0}, {1, 1, 0, 1, 1, 0, 1, 1, 0, 1, 1, 1, 0, 1, 0,
1, 1, 1, 1, 1, 1, 1, 1, 0, 1, 1, 1, 1, 1, 1}, {0, 1, 0, 0, 0, 0, ...
I'm using basic jQuery to render tab data. I was wondering if anybody could comment on how to refactor the click() event handlers, and any general guidance or advice.
Here's the code/output in jsFiddle
Please see snapshot below of the main lines of code I'd like to clean up.
Also be great if ...
I have an issue about being required to insert your code into your question. This can be extremely annoying for many. If you have a large chunk of code, it's also easier for users to understand if you can link your code in, for example, a pastebin paste. It also helps due to the fact that code fo...
I have made this batch code:

To use it copy it in to a txt file and then rename it from .txt to ....
My class is look as follows. My question is how to make it more "professional". It's working right, but isn't this too newbie?

int r = a % b;
if (a < b) {
r = a;

My goal is to take any size number, and convert it to a string of smaller characters that represent the concatenation of the binary expansion of the number. To illustrate what I am talking about, here is an example using the number 4820:
4820's binary: 0001001011011101 # 16 bits of binary,...

@name = gets.chomp

@age = gets.chomp

int func (int a, int b){
if(a < b){
return false; // or 0
}
else {
return true; // or 1

}
Given the Above function, or another similar function that returns boolean true/false, Is it better to return 1/0 or true/false? What is the best practice?
Alternatively would i...
I have the following solution for the Trip problem from Skiena's and Revilla's Programming Challenges (full problem description here).
