st: Problem Using Matwrite, "unrecognized command" error

Subject   st: Problem Using Matwrite, "unrecognized command" error

I am trying to use a user-written code, Matwrite, for converting Stata
to Matlab.  Although it is user-written, I was hoping it would be
frequently enough used by Stata listers to ask a question, as I have
not been able to get it to work, and keep getting the error
"unrecognized command"

I am using Stata 11 on PC.  First, I verify once again that I have
install Matwrite on computer.  I type in "ssc install matwrite,
replace", and Stata shows the following:

. ssc install matwrite, replace
checking matwrite consistency and verifying not already installed...
all files already exist and are up to date.

Next, here is some toy code that I try to call matwrite:

set obs 5000
set seed 1234
gen x = uniform()
gen y = 2*x + invnormal(uniform())
matwrite x y using c:\matlabfile, replace

The last line yields the error: "unrecognized command."

I am not sure why it says this.  If I just type matwrite, it tells me
"using required", as 'using' is a required option for matwrite, so
Stata seems to recognize matwrite somewhere on my computer.  In
addition, an "unrecognized command" error is different from when you
spell something incorrectly / you call something which is not
installed.  For example, if I type "reg_ress" into Stata, I get the
error "unrecognized command:  reg_ress".

Does anyone know why I am receiving this error, and if so, how I might fix it?
