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.
