1. A method of compression of a first numerical matrix, the first numerical matrix being a matrix representation of a dataset and comprising a plurality of data points, the method comprising the steps of:

  • determining the global maximum (x) and global minimum (y) values of the data points in the first numerical matrix;

    creating a representation of a scale of the first numerical matrix, said representation selected from the group consisting of (x,y), (x/y) or (y/x);

    compressing said first numerical matrix using an image compression algorithm to obtain a compressed image file, the image representation of the compressed image file having a global maximum (a) and global minimum (b) wherein (x-y) is different to (a-b); and

    providing the representation of scale and the compressed image file to a transmitter so as to allow a receiving system to reconstruct the first numerical matrix.
