Many numerical codes rely heavily on matrix and vector operations. Think for example of matrix-vector and matrix-matrix products, the solution of linear system of equations, the calculation of eigenvalues and eigenvectors or singular-value decompositions. These operations might be so ubiquitous in the code base or might have to be run on such large data sets that the availability of efficient implementations becomes an absolute necessity in your code. ...
