Optimization. Gauss-Hermite quadrature. Quasi-Newton method.
Hi! I have a problem with estimating parametres b and r. I have integral approximation with Gauss-Hermite quadrature using abscissas (in code xx) and weights (ww). And now I must optimize the log-likelihood function using quasi-Newton method. Here, I wrote what my function (lt) looks like. dt=load('dt.txt'); % Num... 3 Mar 2010 09:31

Color differentiation in plot
Hi, I plot a variable number of lines in a graph. I want every line to be plotted in a different color with as much differentiation in colors as possible. For now i use: cm=colormap; This gives me a predefined set of colors. When plotting, i give every line a different color from this set, with as much distan... 3 Mar 2010 07:20

Trim, how does it works?
Hi, I'm new to this forum and I hope to find some answers to my problems. First of all I'm a begginer in MatLab/Simulink and all I've learned has been learned by myself, no teacher, so probably I lack in some easy fundamentals. By now I'm developing a very simple model, based on first principles to study the dynami... 3 Mar 2010 07:20
