I need to make sequence (1D vector) from 2 constants in Simulink.

e.g.: x1=1 and x2=10 as input constant

Desired vector: X=[1 2 3 4 5 6 7 8 9 10]

I know It is very easy to generate such vector in matlab, but I really want to do it in terms of blocks and not even Embedded Matlab Function Block.

Thanks in Advance

Matlab function is supported by HDL coder. Depends on verision of matlab you are using

Mojtaba, If you hints us about your requirement, may be anyone can suggest a better alternative solution.

Mojtaba: Do x1 and x2 change during simulation? If not, try defining them as workspace variables.

Constant block: Enter [x1:x2] as Value.
MATLAB Function block: Make them non-tunable parameters on the block's Ports and Data Manager and compute output using [x1:x2].

yes they change during simulation.

I think this is a lot harder to do. You will need to understand Variable-Size Signals because if x1 and x2 change during simulation, the size of the signal also changes. I don't see any easy way to do this without the MATLAB Function block, but even with that block, I think this will be tricky.
