  • Linearization of a (sparse) symmetric matrix

    Context I have a symmetric matrix (containing numbers, or sequences of characters) which is eventually sparse (meaning that it contains a lot of zeros). I want to store this matrix in a computer program without loosing too much space. The idea is to create a vector from the matrix (hence we do not duplicate the…

The input of the program is…
