generating periodic signal by matlab

[electroabdo]

Hi,

I want to generate periodic signals of ones and zeros by matlab. It's a periodic signal with active and passive periods, the active period has a value of one and the passive period has zero value. It consists of 7 passive and 6 active periods, starting with passive. Each period is 42 seconds.

Could you guide me through this, thanks.
