Computing Approximate GCRDs of Differential Polynomials
Haraldson, Joseph (University of Waterloo, 2015-09-21)We generalize the approximate greatest common divisor problem to the non-commutative, approximate Greatest Common Right Divisor (GCRD) problem of differential polynomials. Algorithms for performing arithmetic on approximate ... -
Matrix Polynomials and their Lower Rank Approximations
Haraldson, Joseph (University of Waterloo, 2019-08-07)This thesis is a wide ranging work on computing a “lower-rank” approximation of a matrix polynomial using second-order non-linear optimization techniques. Two notions of rank are investigated. The first is the rank as the ...
