Simulink and doing x(k)= x(0) + 2

In simulink I wish to perform. x(k)= x(0) + 2; I know how to initialize variables Using MATLAB command prompt, via x=0. But I don't know how to set up x(k). After the first time iteration has past I'll get:

x(k)= x(k-1) + 2.

I want to be able to do this in simulink, I can do it in MATLAB, but not simulink. Please help.

Best,

Shawn Daniel

x(k)= x(0) + 2 ? this is not what you want. What you want is x(k)=x(k-1)+2 with x(0)=0

Answer 1

set the initial value of x in the unit delay block
