-===== Notations and definitions  =====
-
-Vectors, matrices and higher-order tensors are always boldfaced, with vectors
-given by lower case letter letters and matrices and higher-order tensors given by upper case letters.
-
-Unless otherwise stated, the elements $v_i$ of a vector $\bm{v}$ are assumed to be real. That is a vector of length $n$ is defined as
-$\bm{x}\in \mathbb{R}^{n}$ and if we have a complex vector we have $\bm{x}\in \mathbb{C}^{n}$.
-
-For a matrix of dimension $n\times n$ we have 
-$\bm{A}\in \mathbb{R}^{n\times n}$ and the first matrix element starts with row element (row-wise ordering) zero and column element zero.
