|  | The data type LinearAlgebraTraits_dencapsulates two classesMatrix,Vectorand many functions of basic linear algebra. An instance of data typeMatrixis a matrix of variables of typeNT. Accordingly,Vectorimplements vectors of variables of typeNT. Most functions of linear algebra are checkable, i.e., the programs can be asked for a proof that their output is correct. For example, if the linear system solver declares a linear system \( A x = b\) unsolvable it also returns a vector \( c\) such that \( c^T A = 0\) and \( c^T b \neq 0\).  More...
