only need diagonal elements of huge matrix
I have an optimization problem, hopefully someone can help me. T is an Mxn matrix H is an nxn matrix (M is huge (>500), n is 25 at max) % my way 1: E=nan(M,1); for k=1:M t = T(k,:); E(k) = t * H * t' ; end % my way 2: whatever = T * H * T' ; E = diag(whatever); Although way 2 is faster (really, ... 30 Jul 2010 17:27

Numerical Integration
I am trying to perform numerical integration on a lot of data in order to come up with some calibration plots of sorts. I am needing to integrate Planck's black body emission multiplied by the camera's spectral response with respect to wavelength. Now Planck's equation is a function of wavelength and temperature and ... 30 Jul 2010 09:40
