unrolling which can result in substantially faster code.
Also note that the elements of this matrix are laid out in memory by the layout
object supplied as a template argument to this class. The default_matrix_layout
object supplied as a template argument to this class. The row_major_layout
sets elements down contiguously in memory and in row major order. Additionally,
all memory allocations are performed using the memory manager object supplied as
a template argument to this class.
