Does the command (wrcoef ) represent DWT ??

Hi all,

Does this command ( wrcoef ) represent extracting the signal with wavelet transform representing wavelet discrete transform WDT ? if not then in which kind of wavelet extraction methods we can call it ?

thank you all regards,

[Walter Roberson]

wrcoef() is for reconstructing multi-level 1D wavelets. dwt() is for constructing single-level 1D wavelets. Both fall under Discrete Wavelet Analysis
