Bill Ossmann,
I know that. I will not use MatLab.
Is there anybody how can build the inverse of the erf ?
Thx, Stefan

Stefan,
If you are running VEE 6.0 or higher, the Matlab function erfinv(x) will
calculate the inverse error function.

Hello.
I need help.
I will calculate the "inverse of the complementary error function". But
I have only a formula for the normal error function (erf) and the
complementary error function (erf_c).
I know: inv_erf(1-X)=inv_erf_c(X)
How can I convert erf to the inv_erf ???
Can you send me a formula ???
Thanks
Note:
If you have a formula, you can check it: inv_erf_c(1E-9) = 4.32
. (0 0) .

Subject: [vrf] Serial Direct I/O object randomly returning error 811
I'm using VEE PRo 6.01 on a Windows 2000 PC.
I use the Serial Direct I/O object a lot in my application, to control
equipment connected to 6 different RS232 PC ports. I always use the error
output on any Direct I/O object, to check for errors. I'm often getting an
error with following characteristics (as reported by the errorInfo object):
Number =811
Message=I/O error or timeout occurred with serial interface at 1 (or
whatever the address is)
More[0]=Unable to set the receive buffer size of 4096
The error seems random, I cannot isolate what causes it. I have been using
code ignores the error if it this particular error, but would prefer to
know why its occurring and fix the cause.
I programmatically change some of the properties of each port (like baud
rate and timeouts), but I never alter the receive buffer size. Also, this
error occurs even if the only transaction is a write or close transaction.
Nothing to do with the receive buffer.
It seems like a VEE bug to me, but maybe its something I'm doing. Anyone
else seen this or similar?
Thanks, any ideas are appreciated.
