Good day, I have been playing with this problem for some time now, and can't seem to analyze how to output the array probabilities, using PHP or javascript, had anyone manage to solve this problem, thanks in advance

example:

$arrayNms = [ ["A", "B", "C"], ["Q", "P"], ["CC", "C3"] ]; /* OUTPUT A, Q, CC A, Q, C3 A, P, CC A, P, C3 B, Q, CC B, Q, C3 B, P, CC B, P, C3 C, Q, CC C, Q, C3 C, P, CC C, P, C3 */ //this is what I got so far, but can't seem to output the desired values $arr1 = []; for ($i = count($arrayNms) - 1; $i >= 0; $i--) { for ($j=0; $j < count($arrayNms[$i]); $j++) { $prdName1 = $arrayNms[$i][$j]; if(array_key_exists(($i+1), $arrayNms)){ for ($k=0; $k < count($arrayNms[$i+1]); $k++) { $prdName2 = $arrayNms[$i][$k]; print_r($prdName2.', '.$prdName1); } } } }

thank you very much

This looks like the kind of challenge most textbooks give students to learn about recursive functions. Something like this would provide the desired output, and will work no matter how many arrays of values are in `$arrayNms`

(as long as there is at least one):

function print_values($array, $index = 0, $base = "") { // check if there's another array of values after this one $is_last = !isset($array[$index + 1]); // loop through all values in the given sub-array foreach ($array[$index] as $value) { if ($is_last) { // if this is the last array of values, output the current value echo $base . $value . PHP_EOL; } else { // otherwise, append this value to the base and process the next array print_values($array, $index + 1, $base . $value . ", "); } } } $arrayNms = [ ["A", "B", "C"], ["Q", "P"], ["CC", "C3"] ]; print_values($arrayNms);

Output:

A, Q, CC A, Q, C3 A, P, CC A, P, C3 B, Q, CC B, Q, C3 B, P, CC B, P, C3 C, Q, CC C, Q, C3 C, P, CC C, P, C3

**Multidimensional arrays,** This MATLAB function returns an n-by-1 vector y containing the probability multivariate normal distribution with zero mean and identity covariance matrix, Evaluate the pdf of a two-dimensional normal distribution at a set of given points. Size of multidimensional arrays: The total number of elements that can be stored in a multidimensional array can be calculated by multiplying the size of all the dimensions. For example: The array int[][] x = new int[10][20] can store a total of (10*20) = 200 elements.

In Java

public class MyClass { public static void main(String args[]) { String[][] arr = {{"A","B","C"},{"P","Q"},{"CC","C3"}}; print(arr, 0); } public static void print(String[][] arr, int depth) { if(depth == arr.length) { for(int i =0; i < arr.length - 1 ; i++) { System.out.print(arr[i][0] + ","); } System.out.print(arr[arr.length - 1][0]); System.out.println("\r"); } else { for(int j =0; j < arr[depth].length ; j++) { String temp = arr[depth][j]; arr[depth][j] = arr[depth][0]; arr[depth][0] = temp; print(arr, depth + 1); } } } }

**Multivariate normal probability density function,** ProbabilityDistribution is missing or incorrectly defined. I was lucky find a solution for 2 dimensions that just sets the elements before a default element is needed� The simplest form of the multidimensional array is the 2-dimensional array. A 2-dimensional array is a list of one-dimensional arrays. A 2-dimensional array can be thought of as a table, which has x number of rows and y number of columns. Following is a 2-dimensional array, which contains 3 rows and 4 columns −

In JavaScript:

var myArr = [ ["A", "B", "C"], ["Q", "P"], ["CC", "C3"] ]; for (var el1 in myArr[0]) { for (var el2 in myArr[1]) { for (var el3 in myArr[2]) { console.log(myArr[0][el1]+', '+myArr[1][el2]+', '+myArr[2][el3]); } } } /* A, Q, CC A, Q, C3 A, P, CC A, P, C3 B, Q, CC B, Q, C3 B, P, CC B, P, C3 C, Q, CC C, Q, C3 C, P, CC C, P, C3 */

var myArr = [ ["A", "B", "C"], ["Q", "P"], ["CC", "C3"] ]; for (var el1 in myArr[0]) { for (var el2 in myArr[1]) { for (var el3 in myArr[2]) { console.log(myArr[0][el1]+', '+myArr[1][el2]+', '+myArr[2][el3]); } } }

**How to create multidimensional arrays of distribution objects ,** ndarray , a fast and space-efficient multidimensional array providing vectorized whole arrays of sample values from many kinds of probability distributions. Multidimensional Array Example Program: All we have discussed till there, everything is merged in single program to help you understand the concept about Multidimensional array. Important Note: We have considered the use of for loop because its mandatory to traverse the elements in the array using loop. So we consider two for loops for each array.

Similar to Slawomir's JS answer:

<?php $items = [ ["A", "B", "C"], ["Q", "P"], ["CC", "C3"] ]; foreach($items[0] as $i) foreach($items[1] as $j) foreach($items[2] as $k) printf("%s, %s, %s\n", $i, $j, $k);

Output:

A, Q, CC A, Q, C3 A, P, CC A, P, C3 B, Q, CC B, Q, C3 B, P, CC B, P, C3 C, Q, CC C, Q, C3 C, P, CC C, P, C3

**4. NumPy Basics: Arrays and Vectorized Computation,** Next Chapter: Python, Numpy and Probability Content: Numerical Programming There are two methods to flatten a multidimensional array: flatten(); ravel()� PHP - Multidimensional Arrays. A multidimensional array is an array containing one or more arrays. PHP supports multidimensional arrays that are two, three, four, five, or more levels deep. However, arrays more than three levels deep are hard to manage for most people.

**Changing Dimensions of Arrays,** It's possible to create multidimensional arrays in numpy. Scalars are zero dimensional. In the following example, we will create the scalar 42. Applying the ndim� Each element of a multidimensional array is an array itself. For example, int[][] a = new int[3][4]; Here, we have created a multidimensional array named a. It is a 2-dimensional array, that can hold a maximum of 12 elements, 2-dimensional Array. Remember, Java uses zero-based indexing, that is, indexing of arrays in Java starts with 0 and not

**Functions to Create Numpy Arrays,** homogeneous transition probability matrix, where Pt = P. 2 We propose to use a multidimensional array, A, of dimensions ns � ns � (nt + 1) to� multidimensional array probability.

**[PDF] A Multidimensional Array Representation of State ,** MultiDimensional Array from a discrete Probability Mass Array when Distribution Array of a Probability Mass Array when dimensions > 2,� In cases where you need to perform analytics or two dimensions of data, you use a multidimensional array. The following code shows you how to create a multidimensional array. Dim mystring(0 to 1, 0 to 3) As String . In the above code, a two dimensional array is created. The first dimension contains indexes 0 and 1.

##### Comments

- can we change the $arrayNms to get the desired output ?
- the $arrayNms are from the input fields, anything can be given there
- Uhh this is Java, OP asked for Java
*Script*. - I guess, OP was stuck on the algo not the coding.
