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