how to create a vector in simulink?

[diegoromeres]

hallo!
i simple want to create a vector in a variable to use it more times.
but i don't want to use matlab workspace.
how can i write for example v = [1 2 3] with simulink's blocks?
i have tried by writing in a costant [1 2 3] and then put it in a block 'data store write' but this block want only a number,namely a vector of one dimension.
and second question if i want to write a vector with big dimension for example a vector with 100 elements,better the first 100 elements that in matlab is v = [0 : 1 : 100],how can i do this in simulink?
thanks a lot!

data write?
There are many ways, its all dependent on what you are doing exactly...
1) you can write a embedded function
2) S-function in C language

S-functions compile faster.
