Returns the logarithm matrix for a polynomial matrix.
polylogm(D) // Show the the logarithm matrix of the polynomial matrix D. E=polylogm(D) // Store the logarithm matrix of the polynomial matrix D in the E variable.
Polynomial matrix to calculate its logarithm.
Name of the variable to store the logarithm matrix of a given polynomial matrix.
This function calulates the logarithm matrix of a polynomial matrix using the analytic definition of the logarithm function of a matrix. Use with careful. This function is under development.
t=poly(0,'t') // Define the variable t. D = [t 1-t;t^2 1] // Define a 2x2 matrix with polynomial entries. E = polylogm(D) // Calculates the logarithm matrix of the polynomial matrix D. | ![]() | ![]() |
