Implementation of row vector and the associated operations.
This class provides a data structure for a row vector that contains values of double. It contains also some functions to achieve a set of operations on these vectors.
The vpRowVector class is derived from vpArray2D<double>.
The code below shows how to create a 3-element row vector of doubles, set the element values and access them:
Once build, this previous code produces the following output:
If ViSP is build with c++11 enabled, you can do the same using:
The vector could also be initialized using operator=(const std::initializer_list< double > &)

nrows | : Vector number of rows. This value should be set to 1. |
ncols | : Vector number of columns. This value corresponds to the size of the vector. |
flagNullify | : If true, set the data to zero. |

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

Warning : If you save the matrix as in a text file the precision is less than if you save it in a binary file.

This function performs generalized matrix multiplication: D = alpha*op(A)*op(B) + beta*op(C), where op(X) is X or X^T. Operation on A, B and C matrices is described by enumeration vpGEMMmethod().
For example, to compute D = alpha*A^T*B^T+beta*C we need to call :
If C is not used, vpGEMM must be called using an empty array null. Thus to compute D = alpha*A^T*B, we have to call:
vpException::incorrectMatrixSizeError | if the sizes of the matrices do not allow the operations. |
A | : An array that could be a vpMatrix. |
B | : An array that could be a vpMatrix. |
alpha | : A scalar. |
C | : An array that could be a vpMatrix. |
beta | : A scalar. |
D | : The resulting array that could be a vpMatrix. |
ops | : A scalar describing operation applied on the matrices. Possible values are the one defined in vpGEMMmethod(): VP_GEMM_A_T, VP_GEMM_B_T, VP_GEMM_C_T. |
