How to use different sampling times for 2 blocks in the same simulink model?

I am trying to write a RLS (Root Least squares) algorithm. I am using ode4(Runge-kutta) as my solver with a fixed step size of 0.001 seconds for my mathematical system but for RLS algorithm, I want the sample time to be 0.1 s. I have tried using sleep, pause in the RLS simulink block but doesnot seem to be working as the output I am getting is wrong. The top block is RLS block.

It looks like a MATLAB Function block. Right click it, select "Block Parameters (Subsystem)", specify sample time as 0.1. You might need some Rate Transition blocks to resolve the resulting sample time issues.

Thanks Fangjun Jiang..
