hi, I am stuck in my research (a biometrics project) at a point where i have to find out the solution of the LPC equation. i.e 1/(1- polynomial_in_z). I have 14 LPC coefficients. And I want to solve the LPC equation. Please tell me how can I do this. MATLAB's 'residue' function solves same kind of equation but with a real variable 'x'. In case of the LPC equation the variable is a complex variable 'z'. So the results are not working rightly. Regards, Muhamamd Shahid Munir |
