Detailed Description

Implementation of column vector and the associated operations.

This class provides a data structure for a column vector that contains values of double. It contains also some functions to achieve a set of operations on these vectors.

The vpColVector class is derived from vpArray2D<double>.

The code below shows how to create a 3-element column vector of doubles, set the element values and access them:

#include <visp3/code/vpColVector.h
int main()
{
vpColVector v(3);
v[0] = -1; v[1] = -2.1; v[2] = -3;
std::cout << "v:" << std::endl;
for (unsigned int i = 0; i < v.size(); i++) {
std::cout << v[i] << std::endl;
}
}

Once build, this previous code produces the following output:

v:
-1
-2.1
-3

You can also use operator<< to initialize a column vector as previously:

#include <visp3/code/vpColVector.h
int main()
{
vpColVector v;
v << -1, -2.1, -3;
std::cout << "v:" << v << std::endl;
}

If ViSP is build with c++11 enabled, you can do the same using:

#include <visp3/code/vpColVector.h
int main()
{
#if (VISP_CXX_STANDARD >= VISP_CXX_STANDARD_11)
vpColVector v({-1, -2.1, -3});
std::cout << "v:\n" << v << std::endl;
#endif
}

The vector could also be initialized using operator=(const std::initializer_list< double > &)

int main()
{
#if (VISP_CXX_STANDARD >= VISP_CXX_STANDARD_11)
vpColVector v;
v = {-1, -2.1, -3};
#endif
}

void vpColVector::init ( const vpColVector &  v,
unsigned int  r,
unsigned int  nrows 
)

Initialize the column vector from a part of an input column vector v.

Parameters
v: Input column vector used for initialization.
r: row index in v that corresponds to the first element of the column vector to contruct.
nrows: Number of rows of the constructed column vector.

The sub-vector starting from v[r] element and ending on v[r+nrows-1] element is used to initialize the contructed column vector.

The following code shows how to use this function:

#include <visp3/core/vpColVector.h>
int main()
{
vpColVector v(4);
int val = 0;
for(size_t i=0; i<v.getRows(); i++) {
v[i] = val++;
}
std::cout << "v: " << v.t() << std::endl;
vpColVector w;
w.init(v, 0, 2);
std::cout << "w: " << w.t() << std::endl;
}

It produces the following output:

v: 0 1 2 3
w: 1 2

void vpColVector::insert ( unsigned int  i,

for (unsigned int i=0; i < v.size(); i++)

void vpColVector::reshape ( vpMatrix &  M,
const unsigned int &  nrows,
const unsigned int &  ncols 
)

Reshape the column vector in a matrix.

Parameters
M: the reshaped matrix.
nrows: number of rows of the matrix.
ncols: number of columns of the matrix.
Exceptions
vpException::dimensionErrorIf the matrix and the column vector have not the same size.

The following example shows how to use this method.

#include <visp3/core/vpColVector.h>
int main()
{
int var=0;
vpMatrix mat(3, 4);
for (int i = 0; i < 3; i++)
for (int j = 0; j < 4; j++)
mat[i][j] = ++var;
std::cout << "mat: \n" << mat << std::endl;
vpColVector col = mat.stackColumns();
std::cout << "column vector: \n" << col << std::endl;
vpMatrix remat = col.reshape(3, 4);
std::cout << "remat: \n" << remat << std::endl;
}

If you run the previous example, you get:

mat:
1 2 3 4
5 6 7 8
9 10 11 12
column vector:
1
5
9
2
6
10
3
7
11
4
8
12
remat:
1 2 3 4
5 6 7 8
9 10 11 12

void vpArray2D< double >::resize ( unsigned int  nrows,
unsigned int  ncols,
bool  flagNullify = true,

)
inlineinherited

Set the size of the array and initialize all the values to zero.

Parameters
nrows: number of rows.
ncols: number of column.
flagNullify: if true, then the array is re-initialized to 0 after resize. If false, the initial values from the common part of the array (common part between old and new version of the array) are kept. Default value is true.
recopy_: if true, will perform an explicit recopy of the old data.
