I have a sine signal which has a peroid of 100s, i want the average value of the signal for every 10s. ie. i need 10 average values.

Why don't you take it by hand?
1/10 Integral_10k^10(k+1) Sin(2*pi/100*t) dt = -5/pi*Cos(2*pi/100*t)|_10k^10(k+1) = 5/pi*( Cos(2*pi*k/10) - Cos(2*pi*(k+1)/10) )
as k varies from 0 to 9.

One way is to write the output of sine signals to MATLAB Workspace as an array and from there you can take out values and calculate the average.
