Can anyone suggest a method to convert a univariate polynomial of degree n into a n x n matrix? For example, the polynomial 1 + x^2 + x^3 + x^4 + x^5 converts to [0 0 0 0 1; 1 0 0 0 0; 0 1 0 0 1; 0 0 1 0 1; 0 0 0 1 1], and the polynomial 1 + x^2 + x^5 to [0 1 1 1 1; 0 0 1 1 1; 1 1 1 0 0; 0 0 0 0 1; 1 1 1 1 1]. I cannot make out how this is done. Any leads appreciated.
