Re: Input to external program

I don't know if this old trick can help you.

When you run a dos program which asks for inputs, you can use,

EPDRiv1H.exe <inputs.txt

inputs.txt is a text file, in your case, it contains just one
character 'y' without the single quote.

Try to see if it works for you.

Hi,

I am calibrating a model and need to be able to run it over and
over
100's of times from MatLab. I have figured out how to call the
model
from MatLab using dos or ! but the problem is that once the model
starts to run, a question requiring user input pops up in the
command
prompt (it asks if I want to create a certain type of file while
the
model is running y/n). I need to be able to answer "y". How can I
send this input to the command prompt automatically from MatLab
(since
it will happen 100s of times).

I tried using:

dos('EPDRiv1H.exe &') % to call the EPDRiv1H model
dos('y') % to answer 'y' to the question
that
pops up in the command prompt when EPDRiv1H runs

but that does not work since 'y' is not a system command.

Please let me know if you can help!

Thanks,
Heather
