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++) {
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;
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.
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 just want to know the code of the program: Write code to accept matrix as aurgument and display its multiplication matrix which return its multiplication matrix.
but if the matrix is compressed_matrix type, there's something with it. the error log as below:
Check failed in file boost_1_48_0/boost/numeric/ublas/detail/matrix_assign.hpp at line 1078: detail::expression_type_check (m, cm) terminate called after throwing an instance of 'boost::numeric::ublas::external_logic' what(): external logic Aborted
One thing that I was not able to fully understand even though I read through the section on it a few times, is the for loop. I mean, I understand the premise of (statement, condition, update statement). However, I do not quite understand how a math problem is affected by this.
How this works using multiplication and division? And lastly, why would you use a do.. while loop?
I am a c++ leaner, I am trying to create a BST tree for this expression: 2346*+/8+, and do inorder and postorder to get the in-fix version, and postfix version of the expression. I am having difficulty to create the binary tree for the expression. Here is my peso code:
I made a program that prints out arithmetic sequence.. but problem is that,
when I enter a(first term) =5, d(differnce)=2.4 and n=3 the program prints out only first two terms not three.. for all the other numbers it works correctly..
