ROOT::Math::MatRepStd< T, D1, D2 > Class Template Reference

template<class T, unsigned int D1, unsigned int D2 = D1>
class ROOT::Math::MatRepStd< T, D1, D2 >

Expression wrapper class for Matrix objects.

MatRepStd Standard Matrix representation for a general D1 x D2 matrix.

This class is itself a template on the contained type T, the number of rows and the number of columns. Its data member is an array T[nrows*ncols] containing the matrix data. The data are stored in the row-major C convention. For example, for a matrix, M, of size 3x3, the data \( \left[a_0,a_1,a_2,.......,a_7,a_8 \right] \)d are stored in the following order:

\[ M = \left( \begin{array}{ccc} a_0 & a_1 & a_2 \\ a_3 & a_4 & a_5 \\ a_6 & a_7 & a_8 \end{array} \right) \]
