[Help-gsl] Integration in a long while loop

[Sam M. Vinko]

Hi,
I have noticed that using the gsl integration in a loop will work only  
a certain number of times.  If I take an integral functional and try  
to integrate it in a loop (for a certain set of values of a parameter  
A - say from 1 to 1000) after some values are calculated (for example  
from A=1 to A=10) the error

gsl: qags.c:558: ERROR: roundoff error detected in the extrapolation  
table
Default GSL error handler invoked.
Abort trap

shows up. I thought that maybe the problem was with the integral for A  
= 10 or A = 11, but if I now start the same code at A = 10 I get all  
the numbers up to A = 20, and again the error. This makes me think  
this is a memory issue, so here is my question - is there any other  
way to clear out work space memory than with

gsl_integration_workspace_free ()

? Changing the size of workspace_alloc does not seem to do anything Is  
there something I'm missing?

Thanks,
Sam
