23 Sep 2009	Padefit Rational polynomial fitting Author: Paul Godfrey	Erres, Seis	Thank you very much for this nice function which works perfectly
03 Sep 2009	Simple SVD SVD computation using QR decomposition Author: Paul Godfrey	togi, hendra	i have a project (Robust DWT-SVD Domain Image Watermarking: Embedding Data in All Frequencies). i use DWT, decompose the cover image A into 4 subbands: LL, HL, LH, and HH. can you tell me how to apply svd to each subband image… the program uses matlab. thx

18 Jan 2009	Gamma Compute a very accurate Gamma function over the entire complex plane. Author: Paul Godfrey	Deepak	Its so lovely to see this function on the first search. Extremely handy. Please post some references as well for the theory.
13 Jan 2009	Simple SVD SVD computation using QR decomposition Author: Paul Godfrey	Lei	Could anybody tell me how to evaluate the time required by the SVD. Please kindly note the svd.m called directly by the workspace is a built-in function, which is much faster than the svd.m available on the Matlab website. So which one is more suitable to evaluate the required time? Actually, I am trying to compare a new algorithm with the SVD in computational cost or time. I suppose the built-in SVD function might be faster than the source-code SVD function. Could anybody help me? Thanks a lot for your kindly helps in advance! My email address is huanglei8rsp@yahoo.com.cn.
