Hi there,

I've been trying to use BERtool to compute the BER of one of my
programs. The program is fine because I have used it before without
being called by BERTool and for a given Eb/No I get the expected
results. The problem comes up when I try to use the tool. After doing
all the changes to adapt my program to the template (it is not the
first time I do it) I use BERTool but I get the error message
"Invalid simulation M-file or model".

I suspect that this happen because my function call some other
functions (to encrypt and decrypt the bit stream) and these call some
other functions. In other words I am afraid the function is too
complicated to be called by BERTool. Actually I have included a call
to my encryption function from the provided example "viterbisim.m"
and it doesn't work. When I delete that call it works again.

Is it possible that BERTool doesn't work if you include calls to
other functions? (again, my encrytption function has been tested
before and it works fine).

Thanks in advance.
