Hi all, I work with MATLAB R11 on image compression by wavelets. I need compress ratio about 150 to 1 but MATLAB has worse result after compresion as commercial product (LuraTech). I need compress image 176x176 to 256 numbers (char) but I don't know which coeficient I must save. I ca

Can anyone tell me why the 'wavedec' function in the wavelet toolbox might return approximation coefficients that have the value NaN? I don't know any reason why these coefficients should be anything other than real numbers, and the data that I'm using contains relatively small value
