problem with MATLAB wavelet function

[omidi_sbu]

Does the input signal to the MATLAB wavelet function ( dwt ) have to be a power of two?
i have a speech processing project and i have to add about two seconds of zero at the end!

Of couse not, as long as the length is the multiple of the 2^d, where d is the wavelet decomposition level.
