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>.

Return a column vector with elements of v that are reverse sorted with values going from greatest to lowest.

Example:

#include <visp/vpColVector.h>
int main()
{
vpColVector v(10);
v[0] = 5; v[1] = 7; v[2] = 4; v[3] = 2; v[4] = 8;
v[5] = 6; v[6] = 1; v[7] = 9; v[8] = 0; v[9] = 3;
std::cout << "v: " << v.t() << std::endl;
std::cout << "s: " << s.t() << std::endl;
}

Output:

v: 5 7 4 2 8 6 1 9 0 3
s: 9 8 7 6 5 4 3 2 1 0

Pretty print a column vector. The data are tabulated. The common widths before and after the decimal point are set with respect to the parameter maxlen.

Parameters
sStream used for the printing.
lengthThe suggested width of each vector element. The actual width grows in order to accomodate the whole integral part, and shrinks if the whole extent is not needed for all the numbers.
introThe introduction which is printed before the vector. Can be set to zero (or omitted), in which case the introduction is not printed.
Returns
Returns the common total width for all vector elements.

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

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 <visp/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;

std::cout << "column vector: \n" << col << std::endl;
vpMatrix remat = col.reshape(3, 4);
std::cout << "remat: \n" << remat << std::endl;
