This software package is a complement to the article "K-moduli for log Fano complete intersections". The software package implements a series of algorithms for the study of pencils of quadrics in different dimensions. Given two symmetric nxn matrices A and B the package computes the Segre symbol of the pencil given by the two corresponding quadratic polynomials x^TAx and x^TBx. The user inputs the two matrices and the dimension n, and receives the Segre symbol of the pencil.
