Midpoint Riemann Sum Approximation

Hello. I'm looking for an example of using the Midpoint Riemann Sum Approximation to integrate a function over a vector. My independent variable is 10K data points on a log scale representing different wave lengths. My dependent variable is Planck's Function.

I appreciate your time and consideration.
