Using quad_qags



Hello All,

I am trying to use the quad_qags function to evaluate the following with
respect to x:

P0:(quad_qags(v[1,1]*exp((-%i)*(10)*phi/(0.00197))*x,x,-0.63,0.63));

phi is a variable i have in there for plotting purposes later on in the
code.

And v is calculated from the following sum:

for n:1 thru 11 do for j:1 thru 21 do
v[n,j]:1/sqrt(0.63)*(sum(vectors[n,j][m+11]*exp(%i*2*%pi*m*x/.63),m,-10,10));

vectors is a list with values between 1*10^-6 and 1*10^-7.

When I try this  I do not get the result with the list of the four
elements. Instead I get a list of values that still contain x followed by
the parameters esprel, epsabs and limit. I do not receive an error message
but no value either. I tried this with quad_qag as well and had the same
problem.

Any thoughts on how to get a value?

Thanks!
Ben
