Awaiting some suggestion. Was my question not very understandable? Please let me know how can I offer more elaborate clarification. Additionally, I would like to solve the determinant of "p1" for the values of "z" (I am working with some multivariate time series modelling). When I use det() function, it am getting error that, that function is not for objects with class polynomial. Any idea please? Thanks,

My problem is, if I pass coefficients as simple numerical values, it is working, but for matrix coefficient it is not. Here is my try: library(PolynomF) z <- polynom() ## following is working p1 <- 1- 4.5*z ## However following is not giving results as intended p1 <- diag(3)- matrix(1:9, 3,3)*z In the 2nd example, I was expecting a matrix polynomial in "z" upto degree 1, which I did not get. Can anyone please correct me how to address this problem?
