Re: [Help-gsl] delete function generates an error in movstat.h

[Montezano, Daniel]

Hello there,

Just checking if anyone has come across a similar problem or if anyone has been 
able to reproduce the error with this code.

On my side, so far no luck. Have reinstalled everything and 
recompiled/reinstalled GSL and still the issue remains.

Thanks in advance for any help or suggestions.

Daniel

Hi Patrick,

Thanks for the reply.
The source code I am trying to compile follows below.

The file vector.dat contains the following list of numbers:
12, -20, 12, 24, 23, 8, -19, 9, -4, 2, 3, 4, 1, 7, 6, 7, 0, -1, -1, 2, 44, 1, 
-9, 7, 5, 5, 6, 6, 1, 1

Thanks!

Daniel

Can you provide your source code?
