1. Help: "Randint" in "Read from Wkspace Block" vs "MAtlab Function"

Hi,

In the Communications Toolbox there is a Matlab function, randint, which
creates a vector or matrix of random integers." "Randint(100,1,16)"
typed into the workspace would create something like:

1
5
3
7
3
9
........

When I use simulink to do the same thing, I used the "Read from
workspace" block and then fed the output to a "To workspace" block.

------------                       --------------
|  Read        |                      |    To           |
|   From       | --------------|   WkSpace |
|  WkSpace |                      |                   |
 ------------                       --------------

When I examined the file created in the workspace I saw that all of the
random integers created were repeated.

1
1
5
5
3
3
7
7
3
3
....etc.

What is the difference between using the randint as a matlab function as
opposed to using it in the simulink "read from workspace" block? It
seems as if the simulink model that I am using is writing the workspace
twice a timestep.

I am also a little bit confused about how to write the output of a "read
from workspace" block to a file. the results that I got were a little
bit disappointing.

Thank You
Tom
