Defining material properties

Hi,
How can I define material properties of 3 types of particles? As, I want to use different friction between particle-particle(0.1), particle-bottom wall(0.0) and particle-side walls(0.7). Is this correct way of defining:

fix id all property/global coefficientFriction peratomtypepair 3 0.1 0.0 0.7 0.7 0.7 0.0 0.0 0.7

thanks,
Ram

as written in the manual:
fix id all property/global coefficientFriction peratomtypepair n_atomtypes value_11 value_12 .. value_21 value_22 .. .

best,
Christoph
