Matlab how to create n arrays of equal size matrices from an array of different size matrices
Date : March 29 2020, 07:55 AM
wish of those help I have an array of different size matrices.I would like to create n arrays each including equal size matrices. So if I have: mat =
[4x5 double]
[4x5 double]
[5x5 double]
[4x5 double]
[5x5 double]
[6x5 double]
[5x5 double]
arr_sizes = arrayfun(@(x) size(mat{x},1),1:size(mat,1))'
arr_sizes =
4
4
5
4
5
6
5
[~, ~, idx] = unique(arr_sizes);
tot_arr = arrayfun(@(x) mat(idx == x), 1:max(idx),'UniformOutput',false)';
tot_arr =
{3x1 cell}
{3x1 cell}
{1x1 cell}
tot_arr{1}
ans =
[4x5 double]
[4x5 double]
[4x5 double]

divide and conquer  find median between two arrays of equal size that contain unique elements?
Date : March 29 2020, 07:55 AM
To fix the issue you can do The O(n) meidan of median algorithm actually partitions the array so that the elements before it are less than it and after it are greater than it. When you recurse with the median of medians as pivot, you are partitioning the array so that it looks like

How to check if two arrays of equal size have the same values in C? (complexity O(n) )
Date : March 29 2020, 07:55 AM
I wish this helpful for you Edit: the values of the elements range from 0 to 99 from 0 to 99. Is that even possible? I've tried to use the following code, but it's obviously wrong: , Yes, use hash in C++: #include <iostream>
#include <unordered_set>
bool isEqual(int a1[], int a2[], int len) {
using namespace std;
unordered_set<int> s1(a1, a1 + len); //O(n)
unordered_set<int> s2(a2, a2 + len); // O(n)
return s1 == s2; // O(n)
}
int main() {
using namespace std;
int a1[5] = {5,2,3,4,1};
int a2[5] = {1,3,2,5,4};
std::cout << isEqual(a1, a2, sizeof(a1) / sizeof(int)) << std::endl;
int a3[5] = {0,2,3,4,5};
int a4[5] = {1,6,2,5,4};
std::cout << isEqual(a3,a4, sizeof(a3) / sizeof(int)) << std::endl;
return 0;
}

How to join multiple arrays in ruby which has equal size
Date : March 29 2020, 07:55 AM
wish help you to fix your issue I have the following code: , Something like this should do the trick: chars.map.with_index {char, i
prices[i].zip(names[i], numbers[i], pics[i], [char].cycle)
}.flatten(1)

Implementation of the median of two sorted arrays of equal size in C++
Tag : cpp , By : richardD
Date : March 29 2020, 07:55 AM
Does that help I tried to implement the above algorithm in C++, but somehow I am getting a rounding error when computing the length of half of the array. int size = ceil(size_1/2);
int size = ceil(size_1/2.0f); // now we're dividing by a float, so the result will be noninteger
int size = (size_1+1)/2;
