How to suppress warnings

[Oliver Demetz]

Hi,

I am getting warnings of the kind

"warning
  matrix is close to singular..."

frequently in my code. I know that this can be a problem, but for now I 
have to accept thi fact.

I would like to suppress these warnings so that they are not displayed 
anymore.

How can I realise this?


Further,
since I am using the scilex program to use its output in my own 
application, I have the problem, that even with the

    "-nwni"

switch, scilex asks me

    "more ?"

which I also would like to be answered automatically with "y".

How can I switch off this question?

Thanks in advance
