"SpletTrace of a scalar. A trivial, but often useful property is that a scalar is equal to its trace because a scalar can be thought of as a matrix, having a unique diagonal element, which in turn is equal to the trace. This property is often used to write dot products as traces. Example Let be a row vector and a column vector. " - Trace of block matrix
