Sawtooth signal generation in matlab

Hi! how could i generate a sawtooth signal. the amplitude schould variates between -180 and +180 and with a combination of negative and positive slope? somethig like this:

 %

       +   +   +     +   
     +    +      +    +
    +    +   +    +    +

Thank you. But how could i get this saw tooth combined wit another sawtooth with negative slope?

I mean : from 0 to Tp ->positive slope. And from Tp to 2*Tp ->negative slope

+   +    +       +   
   +    +  +    +  +
  +    +    +  +    +    
+    +       +       +  
-0-------Tp------------2Tp------->t

Thank you
