An efficient algorithm to determine the image of a parallelepiped under a linear transformation
V. Visvanathan, Linda S. Milor · 1986
An efficient algorithm to determine the image of a parallelepiped under a linear transformation is presented. The work was motivated by certain problems in the testing of analog integrated circuits. The method is based on specifying the boundary hyperplanes that define the image polytope and is of polynomial complexity in n (the dimension of the parallelepiped), for a fixed value of the dimension of the range of the linear transformation. The algorithm has been implemented using library routines from LINPACK.
