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 > &)

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:
