我正在尝试使用scipy.io从Matlab5.0文件中读取一些实验条件。问题是输出文件是一系列极其复杂的数组。如何过滤matlab文件中的数据?
import scipy.io as sio
with open("sequence_output.txt", "w") as f:
mat = sio.loadmat("seq_data.seq")
f.write(str(mat))
这在输出文件中给出了类似下面的内容。(实际文件大于800行)。
我如何从这个文件中挑选出我需要的数据?
{'__header__':
该代码实现了快速排序,并利用了通过引用传递列表的优点。我正在寻找性能和一般的最佳实践。
import random
def quicksort(array, l=0, r=-1):
# array is list to sort, array is going to be passed by reference, this is new to me, try not to suck
# l is the left bound of the array to be acte on
# r is the right bound of the array to act on
我有一些javascript (,JSFiddle)
var array = new Array();
array.push('a');
array.push('b');
var index = array.indexOf('b');
array = array.splice(index, 1); // splice out the element
alert(array[0]); // Which one is left?
我希望警报框会返回'a‘,因为'b’正在被删除,但是对话框显示'b‘。
类似地,如果我试图删除“a
我对动态编程很陌生,所以我尝试在下载部分创建一个文件并将其写入Array.txt。逻辑是:
If the Array is longer than the current array: Extend the array and copy to old array onto the new one
但是,我无法找到将旧数组的部分实际复制到新数组上的方法。我现在使用的方式是
System.arraycopy()
下面是代码:(记住用计算机上的当前用户名交换YOURUSERNAME,以避免出现错误)
import java.io.File;
import java.io.IOException;
i
我有一个动态数组,如下所示: const array1 = [];
for(let i = 0; i < 5; i++)
array1.push(i+1); 和另一个数组: let Array2 = Array(6); //Note here the size is 6 as compared to the array1 which has initial size as 5.
for(let i = 0; i < 5; i++)
Array2[i] = i+1; 现在我想在数组的最后追加一个元素,如下所示: array1.push(6); 上
当我在方法public int[] insertionSort(final int array[])中放置数组时,我不会更改array[]
public int[] insertionSort(final int array[]) {
int[] array_for_sorting = array;
final int[]TempArray = array;
int n = array_for_sorting.length;
// printNumbers(TempArray);
for (int j = 1;
public class DataOperations {
int arraySize=50;
int[]array=new int[arraySize];
public void generateRandomArray(){
for(int i=0;i<arraySize;i++){
array[i]=i;
}
}
public int getValueAtIndex(int index){
if(index<arraySize){
System.out.println("Your value At index "+index+" is
我在研究数组。我想知道关于Array.Rank,下面是一个例子:
using System;
public class Example
{
public static void Main()
{
int[] array1 = new int[10];
int[,] array2= new int[10,3];
int[][] array3 = new int[10][];
Console.WriteLine("{0}: {1} dimension(s)",
a
我对Javascript很陌生,现在在Array.push上遇到了一个问题,这就是原型问题。
这是我的代码:
function Ball(array) {
this.array = array;
}
Ball.prototype.allArray = []; // this is a property shared among ALL Ball object, though here I just create one object...
Ball.prototype.addArray = function() {
this.allArray.push(12);
}
我指的是这个站点上的代码:
public static void Shuffle<T>(T[] array)
{
var random = _random;
for (int i = array.Length; i > 1; i--)
{
// Pick random element to swap.
int j = random.Next(i); // 0 <= j <= i-1
// Swap.
T tmp = array[j];
array[j] = ar
我很难将字符串数组值复制到新的字符串数组中。
例如:
String[][] array = new String[3][2];
array[0][0] = "hello";
array[0][1] = "1";
array[1][0] = "guys";
array[1][1] = "2";
array[2][0] = "good ";
array[2][1] = "3";
array = new String [5][2];
all the value in the first array to
我对C非常陌生,我正在尝试制作一个基本的合并排序程序。当我编译这个代码时(使用GCC)
int join(int arrayA[],int aLength,int arrayB[],int bLength)
{
int array[aLength+bLength];
int uptoA = 0; int uptoB = 0;//the upto variables are used as the index we have reached
while ((uptoA < aLength) && (uptoB < bLength))
{
我有以下代码:
main() {
int array[5] = {3,6,9,-8,1};
printf("the size of the array is %d\n", sizeof(array));
printf("the address of array is %p\n", array);
printf("the address of array is %p\n", &array);
int * x = array;
printf("the address of x is %p
