You may need to supply more information to get help. For me, the questions would be:
1. What do you mean by "a confidence interval for a pdf"? Usually confidence intervals are computed for distribution parameters, not for entire pdfs.
2. What is the normal-uniform distribution?
3. What is in the [1,10000] vector?
4. What is the format of the data from which you want to compute the CI? Are these individual observations from the distribution, probabilities of observations being in certain bins, ...?
