i have 12 vectors of size 1*150 (1 row 150 columns)
i want to merge all these 12 vectors to a matrix of size 12 *150 (12 row 150 columns)
all vectors are of same size 1* 150 andAll of them have to join into a matrix of size 12* 150
say vectors are (A1 A2 ... A12) TO a single matrix A(size 2 * 150) I AM USING MATLAB
Code:
#include <iostream>
#include <istream>
#include <fstream>
#include <vector>
[Code]....
Why is it reading in nothing for the arrays, and also making the size of the total thing the total number of numbers? It should have a size of 2, not 5.
I want to convert the matrix to vector and vice verse.

I have a struct that I'm writing in C and need to use a mex function to use it in matlab. The struct was originally in matlab and need to have the variables:
force = feval(forcing, Euler, Euler.x(:,k));
q = squeeze(q(:,k,:)/>/>);
q0 = squeeze(Euler.q0(:,k,:)/>/>);
nx = Euler.nx(:,k);% normal vector
J = Euler.J(1,k);
rx = Euler.rx(1,k);
qh = reshape(qh(k:k+1,:)/>/>,[],1);
k = k;
The mex function I have come up with is:
#include "mex.h"
/* Extract local info for element k */
/* local struct */
typedef struct {
double force;

I have an application thats has been coded in C#. After build it generates a standalone dll file and the exe file.
I want to use this code in Matlab. I found out from this page that I can load the C# classes or codes into Matlab.

I have the code and the application buty unfortunately I do not understand C# at all. So after using this command I was able to see a .NET object in my workspace and this is what I got for its properties and its classes:

I have en error translating a function from Matlab to C/C++ :
Code:
radius(floor(rows/2+1),floor(cols/2+1)) = 1;
% Get rid of the 0 radius value at the 0
% frequency point (now at top-left corner)
% so that taking the log of the radius will
% not cause trouble.
What I did is:
Code: radius[rows/2][cols/2]=1;

I have written code that saves a matrix to a utf-8 file. This code works just fine when invoked from a win32 console app, but if I attempt to use the exact same code by invoking it within a SDI Doc/View Serialize(CArchive& ar), if(ar.IsStoring), it fails, but in a somewhat unusual manner. Namely, the file shows up in the designated directory, but it is an empty file (0 bytes), and the 'Unable to open file' message is seen in Debug config. Note that both the win32 console app and the SDI app are both using a Unicode character set, however, only the SDI app uses the method inside a Serialize(CArchive& ar) method, whereas the win32 console app evokes the save method directly from within _tmain. Why this seemingly illogical disparity occurs.
Here's the template code I have used in innumerable applications to save matrices to a disk file.
Code:
namespace TNT {
// saves a TNT double matrix, discriminating between real and complex matrices by virtue of the respective file markers, 'MATCALC94R' and 'MATCALC94C'.
template <class T>
void SaveRealBMatrix(const Matrix<T> &M, string sfilename) {
_RPT0(0, "SaveRealBMatrix:
");
_RPT1(0, "sfilename =: |%s|
[Code] ....
Here's the code from the SDI document Serialize(CArchive& ar) that fails as described above. Note that m_M is a class member TNT::Matrix<double> m_M that has been verified to exist in the Serialize method.
Code:
void CMyWndDoc::Serialize(CArchive& ar) {
if (ar.IsStoring()) {
CString csFileName = ar.m_strFileName;
wstring ws = csFileName.GetBuffer(0);
string s(ws.begin(), ws.end());

I am trying to simulate the logical circuits having NAND gates. I am reading the structure from .bench file. The structure of a circuit looks like below:
Code:
INPUT(1)
INPUT(2)
INPUT(3)
INPUT(6)
INPUT(7)
10 = NAND(1, 3)
11 = NAND(3, 6)
16 = NAND(2, 11)
19 = NAND(11, 7)
22 = NAND(10, 16)
23 = NAND(16, 19)
It can be seen that the inputs for Gate 22 are 10 and 16 which are also NAND gates. On the other hand, for gate 10, the inputs are 1 and 3 which are simple inputs. So, i need to sort the gates topologically. Although topological sort will not affect the output for this particular example but i have big circuits also in which topological sort is required. But we can use this simple example to do the topological sort.
My effort:I thought to create a map which will keep the information about the gate name and its indegree. But i am unable to proceed further.
Code:
void Circuit::topologicalSort()//topological sorting (for the mixed circuits) {
int counter = 0;
std::map<string, int> unsortTopoList; //this list keeps a track of gate name and its Indegree
for(int i=0; i<gates.size(); i++) {
[code].....
i want to know how i can solve this question? do i need to create a class or write the program codes.

I am trying to write a program that counts specific words that a user inputs "Howdy/howdy/Whoop/whoop" (yes I go to Texas A&M, hence those specific words) I am having an issue where it wont count the first word even if it is "Howdy"
For example if I put it:
"Howdy howdy whoop Whoop" - it only outputs that it counted 3 words
now if I were to do:
"Hello Howdy howdy whoop Whoop" - it would count 4.
Code:
#include "std_lib_facilities_4.h"
int main(){
cout << "Please enter desired words, when you have entered all words, please type CTRL+d (EOF Command)

What happens is, after having called the collisionDestroy-function and the program tries to execute the nest loop in the outer for-loop, it all crashes with the text "Expression: vector iterator not decrementable", which I understand is because the iterator will have already become useless. The question is: know this, how do I fix it? I can't seem to get a hang of it.
Here's the collisionDestroy-function (the collisionReaction does nothing but sets a few local variables):
void Enemy::collisionDestroy(std::vector<Sprite*>& sprites) {
for (std::vector<Sprite*>::iterator iter = sprites.begin(); iter != sprites.end(); iter++) {
Enemy* tmp = dynamic_cast<Enemy*>(*iter);
if (this == tmp && collisionType == 3 || collisionType == 1) {
sprites.erase(iter);
break;
}

I have N vectors which look like this:
[1→m] [m+1→2m] [2m+1→3m] [3m+1→4m] [4m+1→5m]..... [{(N-1)m}+1→Nm]
I want to select 1 element from each vector without duplication of any combinations. Essentially only when all combinations are done with 1st element in first vector ,only then it should move to next element in first vector.
Say i have elements :[123] [456] [789]
my combinations should be like
147
148
149
157
158
159
167
168
169
247....
Also, I cant have any repetitions and only after all combinations of 1 are done only then the loop has to move to next combination ie 247 combination and so on.
I tried NCK (n choose k) command but it gave me random combinations. How should i go about it with using minimal for loops?

First line shows row and column number
First index of the second line tells the number of non-zero entries of the first row and second index tell the column number where the non zero entry is placed
for 1st row of matrix:
non-zero entries=2
column number=1
non-zero entry=3
column number=2
non-zero entry=2
covert this in the given form
0 3 3
2 0 0
0 0 6

I have a cpp app that reads in a number of files and writes revised output. The app doesn't seem to be able to open a file with a ' in the file name, such as,
N,N'-dimethylethylenediamine.mol

Code:
// opens mol file, reads in rows to string vector and returns vector
vector<string> get_mol_file(string& filePath) {
vector<string> mol_file;
string new_mol_line;
// create an input stream and open the mol file
ifstream read_mol_input;
read_mol_input.open( filePath.c_str() );
