C++ :: Find Biggest Part Of Column Over Diagonal Of Matrix
Jan 23, 2013
How to find the biggest column of the matrix (higher of main diagonal) Here is the draft of code that i desighned/ Of cause it has a several mistake. My task is here to create the matrix, allocate the dynamic memory for it, and to find the biggest sum of the column elements that is located over main diagonal. So main points is correct memory allocation, and the sorting to the biggest sum of column higher than diagonal.
#include<iostream>
#include<conio.h>
#include<time.h>
using namespace std;
Here is the draft of code that i designed. My task is here to create the matrix, allocate the dynamic memory for it, and to find the biggest sum of the column elements that is located over main diagonal. So main points is correct memory allocation, and the sorting to the biggest sum of column higher than diagonal.
I made the code that stores and prints 5 row by 5 column values but how to find the largest number from them.What should I do to find the largest number?If I use if-else then it would be very tedious but I think there is way out with for loop but still I can't frame the logic. Here is the code
Code: #include<stdio.h> main() { int lnum[5][5]; int i,j; for(i=0;i<=4;i++) {
I'm having this issue where my else if statements are not working. My program only works correctly when I go into my if statement and change the first part of my array to the specific row I am trying to find ex [0][i] to [1][i].
int getMonthMax(int scores[][COLS],int month){ int highestN=0,i, j; for (i=0;i<ROWS-1;i++){ if(scores[0][i]>highestN){ highestN=scores[0][i];
i want to write a program which find the biggest prime factor of a number for example the biggest prime factor of six is three or the biggest prime factor of fifteen is five. What is my program bug
Code:
#include <stdio.h> // main functions #include <math.h> // for sqrt function int main() { int i, j, k, f; // F = Flag; printf("Enter K
I am new in c programming and my teacher gives me home word to do. the home work is to create dynamic matrix that check if i have same number in row or in column. for example the matrix
1 2 3 2 3 1 3 1 2
is legal matrix and this matrix is illegal
1 3 3 2 1 3 3 2 1
I created the matrix and sent it to function but there I don't know how build the code.
I am having a little bit of trouble with what should be a simple part in my code. For some reason it keeps looping the name part of the program and I seem to be passing over the problem in the code.
Here is the code:
#include <iostream> #include <string> using namespace std;
The first loop will print out all of numbers in the velocity column. The second while loop is looking for the maximum value in that column. It is supposed to print out the max velocity in the end of the second loop. However, when I build and run the program, it's crashed. I run debugger and received "Segmentation fault" error. When I eliminate the second loop, it run just fine I use Code::Block for text editor.
The method doesn't work properly, the point of the code is to tell the minimum value in the given matrix "m", it's supposed to take the first value of the matrix store it in min_ and then compare it to every value of the matrix, if the value stored in min_ is bigger than the current value in the loop then it's stored as the new min_ and at the end it's supposed to print that minimum...
Code: #include <stdio.h> #include <stdlib.h> #define SIZE 3 void minimum (int mat[SIZE][SIZE]){ int r,c; int min_; printf("
I want to get non-singular matrix with the C++ linear algebra library eigen, but I do not know which function works.
assume that X is matrix with dimension of 100*50. I want to get (X.transpose()*X).inverse() in C++, but error is that singular matrix occurs. Multicollinearity occurs in some columns of matrix, i just want to get non-singular matrix. Here is the matrix pivot in R software:
qr(X)$pivot
and the result is: qr(X)$pivot= 1 2 4 5 7 10 ..(11-41).. 42 45 49 50 3 6 8 9 43 44 46 47 48, that is non-singular matrix contains columns except for 3 6 8 9 43 44 46 47 48
I've written the code for the row-wise sum of a matrix:
int rowsum=0; //row-wise sum cout<<"Row-wise sum:"<<endl; for (int i=0;i<m;i++) { for (int j=0;j<n;j++) { rowsum+=arr[i][j]; } cout<<rowsum<<endl; rowsum=0; }
It works fine but I can't figure out how to do the column-wise sum.
I am really desperate on trying to make my code work. The code is to find the eigen values of any given matrix of dimension NxN. The input can be the diagonal of any NxN matrix alongwith its subdiagonal. The code works fine for N~350 or so but when i go beyond that these errors appear.
First-chance exception at 0x00425ea4 in divide.exe: 0xC0000005: Access violation writing location 0x01141000. Unhandled exception at 0x00425ea4 in divide.exe: 0xC0000005: Access violation writing location 0x01141000.
But as i have never declared any variable statically and when i dynamically allocating memory with variables it should work like it does for smaller N values.
I have a problem with searching chars by diagonal not only the main, i have a chars in vector and I need to go though all possibilities (as shown in picture) the word has to be side/2 long so here i have 9, so word has to be 4 chars long how I need to do this?
I am trying to learn so much C as possible by my own. I have learned a bit already and made my first game. I made a tictactoe with a 3x3 board that works great. But now i want to make it a NxN-board. But the problem right now is my checkwinner-function. I really don't know how I should check the diagonal for winner in the for loop. Earlier I have checked the diagonal manually like you can see down there.
I'd have to print the elements in italics. I've tried this:
for (i = 1; i < a.GetLength(0); i++) { for (j = i-1; j >=0; j--) Console.Write("{0,-2}", a[i, j]); Console.WriteLine(); }
with the array mentioned above but for some reason it keeps printing the elements BELOW the line, when I need it to print those above it. I know that for arrays we usually start loops with a value of 0 but seeing as there should be nothing to print at [0,0] I started the loop at 1.
I'm supposed to find the biggest number (largest value), in any given array A with n numbers. (no floats)
My thoughts here are, check if A[0] > A[1]. if yes, check if A[0] > A[2]. If no, check if A[1] > A[2] etc.
I'm not sure how I can do this in code. I'm thinking if A[0] > A[1] is true, then set A[0] = A[k]. Kind of set it aside, and use that for the next if test. But I'm not sure how to do it.
This is my code so far.
Code: int main(){ int A[7] = {12, 6, 9, 33, 2, 25, 53}; int i, k; k = 0;
[Code]....
I'm aware of the flaws here, but this is the best I can do so far. How can I get the if test to use A[k] next, as A[k] will always be the biggest value?
