I have been trying to generate the Battle-Lemarie wavelet and scaling functions I have had some problems in implementing the algorithm given in Mallat's paper in that I do not get enough points in the basic scaling function phi(0,0). When I dilate this function, I am not able to evaluate the dilated function wherever I like because of the lack of points. While implementing an alternative algorithm given in Daubechies' book ( spline scaling function to Battle-Lemarie scaling function via "orthonormalization trick") I get sufficient points but the spectrum is not coming out right. I would appreciate any hints on generating the basic wavelet and scaling functions in the Battle-Lemarie case. Please e-mail or post replies. Ravikanth Pappu EE Dept, Villanova University.
