How to convert a scalar to a vector in Simulink?

I want to convert a scalar, for example 3, to a vector with dimension 3: [0 0 0]

Is posible this?

Do you mean you want it to be a vector like:

   3
to 

   [3 3 3];

Or a variable length vector? You can define the size of a vector before you start the simulation but not during. Both methods are possible.

In simulation, I got a scalar number, for example, 2 or 3 (variable value). Can I get (with this value) a vector(variable length) in simulink?

This wouldn't really work with a complicated system for a number of reasons, but if your model is simple you can use a series of enabled subsystems that can be enabled when the proper constant is selected.
