Hi, I need compute thousands of integrals of the form \int_{0}^{t} \frac{e^{at}}{\sum_{i=1}^n b_i e^{c_i t}} dt. I know that : the time frame [0,t] is typically small (say t \le 1) rates a,c_1,...c_n are of order 1e-4, 1e-5 weights b_1,...,b_n are of order 1. For the moment, I use the very dum…

Looking for a quadrature rule

Yep there was, just fixed it. I am having trouble showing the integral centered i do not know why.
