how to create a matrix in embedded matlab function

I try to fill a matrix in Embedded Matlab Function in simulink with values from 10 to 200, where X(i+1)=X(i)+10.

X(1)=10 X(2)=20 ... X(N)=200

Looks like a simple thing to do, but in Matlab 7 formula start:stride:end as well as a for-loop doesn't work. I can only use this version of Matlab. Anybody can help?
