club multiple boolean time domain waveforms into a single waveform with decimal radix in MATLAB

Hi all, I want to club multiple boolean time domain waveforms into a single waveform with decimal radix in MATLAB. In other words I want to create a single bus which represents the decimal value of the multiple boolean time domain waveforms JUST LIKE THE SIMULATORS USED FOR DIGITAL DESIGN e.g. XilinX, Synopsys

an someone give how to do ir what is the code for this??
