how to provide first order derivative to a constrained least square problem? 6 29 (11/1/2007 10:08:13 PM) comp.soft-sys.matlab Hi all, This is a constrained least square problem. min sum ( (f_i (x_i) - d_i)^2, i from 1 to n) subject to sum(exp(-x_i), i= 1 to n) = 1. Here f_i's are our functions, d_i's are data. I can compute the d... Vista

urgent help! How to solve 2D ODEs numerically in Matlab? 1 13 (10/20/2007 5:53:52 AM) comp.soft-sys.matlab Hi all, I know how to solve numerically a system of ODEs with respect to one variable, say t, in Matlab. But what if I have a system of ODEs involving derivatives with respect to two variables, say t and w.... Vista
