how to do wavelet transformation in real time?

Hello i'm using dyadic filter bank and discrete wavelet transformation. in the simulink we have to set the number of level based on the input signal follow the following expiration 2^n ok then how about if the input signal changing in the real time? I mean the input signal is continuously changing in real time? is there any other block can be use for concious analysis?

Hi are you using dsp.DyadicAnalysisFilterBank? In that case the input signal must be a multiple of four along its first dimension. If you have the Wavelet Toolbox, then you can use wavedec() inside of a MATLAB function block. wavedec() is supported for code generation. That will work on an arbitrary length input signal length, however, you can't expect the wavelet and scaling coefficients to be the same length if the input signal is changing length.
