two questions on 'gamultiobj' function
Dear all, I have two questions on the ‘gamultiobj’ function in obtaining Pareto front. 1 by default, the ‘ParetoFraction’ is 0.35. Does it mean I only take the 35% of the individuals in the first front, i.e., the one with the highest rank? 2 in calculating the crowding distance of each indi... 17 Oct 2009 20:36

Ezplot constants?
I want to plot some quadratic functions with varying coefficients, for example: syms x syms y ezplot('2*x^2 + 3*y^2 = 1') but I want to iterate/vary the '2' and '3' in that expression, something like a = 2 b = 3 ezplot('a*x^2 + b*y^2 = 1') but of course a and b aren't recognized inside the ' ' . How sh... 19 Oct 2009 09:41

gevfit(x,alpha,options)
Hallo Guys out there, I trying to find out how the gevfit function/ parts of it work. I know it is based on the max likelihood funtion, which means you do partial df/dparameter for the distribution f and its paratemeters. With this knowledge I tried to find out whether this part in the gevfit function does this... 19 Oct 2009 07:30
