class ROOT::Math::MatRepStd<float,2,2>


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 \f$ \left[a_0,a_1,a_2,.......,a_7,a_8 \right] \f$d are stored in the following order:
\f[
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)
\f]
